Your body gives you a variety of physical signals when you’re most fertile—if you know what to look out for.

If you’re trying to conceive (or trying to avoid pregnancy), knowing when you’re ovulating is key. You’re in luck—your body actually gives off a variety of signs of ovulation to let you know when you’re in your fertile window. From changes in cervical mucus to cramping, there are many different physical signs of ovulation you can point to.

Recognizing the signs of ovulation empowers you to take charge of your reproductive health, whether you're actively trying to conceive, prevent pregnancy, or simply stay informed about your body's amazing rhythm. Here’s your go-to guide on what ovulation is, when it happens, signs of ovulation, and full-proof methods for understanding when you’re ovulating.

What is ovulation?

Ovulation is the time when one of your ovaries releases a mature egg. The mature egg then travels down the fallopian tube, ready to be fertilized by sperm. If sperm are present in the fallopian tube when you’ve ovulated, the sperm can then fertilize the egg—the first step toward pregnancy.

Ovulation occurs once in your menstrual cycle, usually around 14 days before your next period. However, ovulation may happen earlier or later depending on the length of your cycle—and that’s totally normal. Understanding your specific ovulation time frame is essential if you want to optimize your chance of conception or avoid it naturally.

How long does ovulation last?

Ovulation typically only lasts about 24 hours. The egg is released from the ovary, then travels down the fallopian tube. If the egg is not fertilized after about a day since its release, it will dissolve.

What about the fertile window?

Is your fertile window only a day, too? No, the fertile window—or the best time to have intercourse if you want to get pregnant—is a bit wider than that. The fertile window is six days: the five days leading up to ovulation, and the day of ovulation.

Ovulation and the fertile window are different lengths because sperm can survive for multiple days—typically up to five—in your reproductive tract. This means that if you have sex in the days before ovulation, the sperm can stay in your fallopian tube, then fertilize the egg when its released during ovulation.

If you’re trying to conceive, it’s crucial to not only know when ovulation is happening, but when it’s about to happen—so you can have intercourse in the days leading up to it. 

Signs of ovulation

Whether you’re trying to conceive or not, your body isn’t shy when it comes to showing signs of ovulation. By paying attention to subtle clues, you can see the physical (and sometimes even emotional and mental!) signs of ovulation.

Changes in cervical mucus

Just before ovulation, the hormone estrogen peaks. This rise in estrogen makes your cervical mucus clear and stretchy. Many people often compare the look of this mucus to egg whites.

Your cervical mucus doesn’t just change to let you know that you’re ovulating—it’s actually a way to make it easier for the sperm to get through your vagina, into the uterus, and to your fallopian tubes. If your mucus was thicker or more white versus clear, it would be harder for the sperm to make its way through.

Basal body temperature

Your basal body temperature (BBT) is the temperature of your body at rest. Right before ovulation, your BBT dips, then has a sustained rise that lasts until your next period.

Your BBT changes because of the increase in progesterone after you ovulate. After you ovulate, progesterone rises to prepare the body for pregnancy, which signals to your hypothalamus to set a higher BBT.

You can tell you’re ovulating if you see a slight dip in BBT, then a sustained rise of about 0.5°F. 

To measure BBT, you need to be incredibly consistent and precise to get an accurate reading. You can use a digital thermometer to measure your temperature, and take your temperature at exactly the same time each day.

Ovulation pain

About 40% of people with a menstrual cycle also experience lower abdominal pain when they’re ovulating. This pain can range from light discomfort to agonizing pain, and sometimes it may last a few minutes, but other times it may last for hours or even a day. The pain, also known as mittelschmerz because it happens at the middle of your cycle, typically occurs on the side of your ovaries that the follicle is developing on.

While ovulation pain may feel similar to period cramps, the main difference is when this pain occurs. Ovulation pain happens in the middle of your cycle, about two weeks before your period, while period cramps happen at the end of your cycle, around when you get your period.

Increase in sex drive

If you feel a natural boost in libido, it could be your body trying to optimize your chances of conception. 

Many people feel an increase in sex drive mid-cycle. Estrogen can play a key role in libido, and estrogen peaks right before ovulation, which may make you more interested in sex when you’re ovulating.

Cervical position

Not only does your cervical mucus change when you’re about to ovulate, but your physical cervix changes, too. Before ovulation, your cervix becomes softer, higher, and more open as estrogen increases and attempts to make it easier for sperm to move throughout your uterus.

You likely won’t be able to feel any changes to your cervix from the outside, so detecting changes in your cervical position means you’ll have to check inside. To safely check your cervix, be sure to wash your hands and get into a comfortable position (usually squatting, sitting on the toilet, or standing with one leg propped up). Then, gently insert one or two fingers into your vagina until you reach the cervix—it will feel firmer and rounder than the surrounding vaginal tissue.

To determine if your cervical position has changed before ovulation, pay attention to:

  • Height: the cervix tends to be higher, closer to the back
  • Firmness: it may feel softer and more open
  • Openness: you might feel a slight opening at the tip

How can I tell if I’m ovulating?

Now that you know the signs of ovulation, how can you know for sure if you’re ovulating?

Besides tracking BBT, watching for changes in your cervical mucus, and noticing any ovulation pain or increased sex drive, there are a few ways to track your ovulation with varying degrees of accuracy.

Monitoring cycle length

Ovulation typically happens in the middle of your cycle, around day 14 of a 28-day cycle. If you track your period, you can estimate when ovulation will occur.

While this method can help give you an idea of when you’re ovulating, it can have varying degrees of accuracy—especially if you have irregular cycles, or a cycle of a different length than 28 days, which the majority of people with menstrual cycles have!

Ovulation predictor kits

Ovulation predictor kits measure your hormones to determine when you’re ovulating. Right before ovulation, estrogen rises, leading to what’s commonly known as the luteinizing hormone (LH) surge

While the LH surge is key to pinpointing ovulation, traditional OPKs won’t be accurate for everyone:

  • They’re not reliable if you don’t have standard hormone levels: Often, traditional OPKs look for an LH surge in a “standard” range. However, it’s quite possible that if you have lower or higher LH levels, and you surge out of that range (but still experience an LH surge), the OPK won’t capture that data.
  • They may be harder if you don’t have a 28-day cycle: Like standard cycle tracking, not having a 28-day cycle (which is normal!) can make things a little more complicated. With traditional OPKs, there’s not much guidance on when to test, which means you can end up testing on the wrong day and missing your ovulation.

Tracking hormones throughout your cycle

Finally, you can track multiple hormones throughout your cycle to get a holistic, specific view of what’s happening during your cycle and when. You’ll want to track hormones like:

  • Estrogen, to understand when the hormone rises before ovulation
  • Luteinizing hormone, to understand when your LH surges to indicate ovulation
  • Progesterone, to see if it rises to confirm ovulation

Measuring your specific hormone levels—instead of comparing them with a standard—ensures you can see the patterns in your cycle and get the most accurate data for you.

Signs of ovulation: the bottom line

Whether you’re trying to conceive, trying to avoid pregnancy, or hoping to learn more about your hormone health, learning the signs of ovulation can help you understand this crucial moment in your cycle. From cervical mucus to increased sex drive, your body leaves subtle cues to indicate that you’re ovulating. To confirm that what your body is saying is true, you can use a traditional ovulation predictor kit, or track your hormones for an even more accurate, specific reading.

perimenopause-periods
Should I still see my gynecologist if my periods are just "weird" but not painful?
Yes. Annual visits remain important during perimenopause. Your provider can help determine if your "weird" periods are typical perimenopause changes or something requiring attention. They can also discuss management options to improve your quality of life.
perimenopause-periods
How long do irregular periods last before menopause?
Irregular perimenopause periods typically last 4 to 8 years before your final period, though this varies greatly. Some women experience irregularity for just a few months, while others have irregular periods for over a decade before reaching menopause.
perimenopause-periods
Is it normal to have two periods in one month during perimenopause?
Yes, this can happen, especially in early perimenopause when cycles shorten. You might have a 21 day cycle, meaning you could have a period at the beginning and end of the same calendar month. Track these patterns to distinguish between short cycles and abnormal bleeding.
perimenopause-periods
Why are my periods suddenly so heavy in my 40s?
Heavy perimenopause periods often result from estrogen dominance. When progesterone drops but estrogen remains high, your uterine lining builds up more than usual, causing heavier bleeding when it sheds. This is common in perimenopause but should be evaluated if it affects your daily life.
perimenopause-periods
Can I still get pregnant if my periods are irregular during perimenopause?
Yes. As long as you're having periods, even irregular ones, you may still be ovulating. Pregnancy is possible until you've gone 12 full months without any period. If you don't want to become pregnant, continue using contraception throughout perimenopause.
perimenopause-and-weight-gain
Can you prevent perimenopause weight gain completely?
While you may not prevent all weight changes during perimenopause, you can minimize gain through proactive strategies. Starting strength training before perimenopause, maintaining consistent sleep habits, and managing stress can help your body adapt to hormonal changes more smoothly. Remember, some body changes during this transition are normal and healthy.
perimenopause-and-weight-gain
At what age does perimenopause weight gain typically start?
Perimenopause weight gain can begin in your late 30s or early 40s, often coinciding with the first hormonal changes. Many women notice gradual changes starting 5 to 10 years before their final period. The timing varies greatly based on genetics, lifestyle, and overall health.
perimenopause-and-weight-gain
Does everyone gain the same amount during perimenopause?
No. Perimenopause weight gain varies significantly. Some women gain 5 pounds, others 20 or more, and some maintain their weight. Factors include genetics, starting weight, activity level, stress, sleep quality, and how dramatically hormones fluctuate. Your experience is unique to your body.
Is perimenopause weight gain different from regular aging weight gain?
Yes. While metabolism naturally slows with age, perimenopause weight gain has distinct characteristics. The hormonal shifts cause fat redistribution to the midsection, even if overall weight doesn't change dramatically. This abdominal weight gain pattern is specifically linked to declining estrogen and progesterone, not just aging.
perimenopause-and-weight-gain
Will the weight come off after menopause?
Perimenopause weight gain often stabilizes after menopause when hormones level out, but the weight doesn't automatically disappear. The metabolic and body composition changes that occur during perimenopause tend to persist. However, with consistent healthy habits, weight management becomes more predictable post menopause than during the fluctuating perimenopause years.

Can I take progesterone if I'm breastfeeding?
Yes, progesterone is generally safe while breastfeeding and doesn't significantly affect milk supply. However, always discuss with your healthcare provider before starting any hormone supplementation while nursing.
https://www.oova.life/blog/progesterone-supplementation-guide
Is it safe to take progesterone throughout pregnancy?
Yes, when prescribed by your healthcare provider. Progesterone supplementation in early pregnancy is safe and can reduce miscarriage risk in women with low progesterone or a history of pregnancy loss. Most providers continue supplementation through the first trimester (weeks 10-12) when the placenta takes over.
https://www.oova.life/blog/progesterone-supplementation-guide
Can progesterone supplementation cause weight gain?
Progesterone can cause temporary water retention and bloating, which may show up as a few pounds on the scale, but it doesn't cause true fat weight gain. Most women don't experience significant weight changes from progesterone supplementation.
https://www.oova.life/blog/progesterone-supplementation-guide
Can I switch from pills to suppositories or vice versa?
Yes, but only under your doctor's guidance. The dosing and timing may need adjustment when switching between forms since they're absorbed differently. Never switch on your own, especially if you're pregnant or undergoing fertility treatment.
https://www.oova.life/blog/progesterone-supplementation-guide
Will progesterone supplementation delay my period?
Yes, progesterone keeps the uterine lining intact, so if you're not pregnant and continue taking progesterone, your period will be delayed. Once you stop taking it, your period should start within 2-10 days. If you are pregnant, progesterone helps maintain the pregnancy and you won't get a period.
https://www.oova.life/blog/progesterone-supplementation-guide
Should I take progesterone pills orally or vaginally?
For fertility and pregnancy support, vaginal progesterone is usually preferred because it delivers higher concentrations directly to the uterus. For perimenopause or general hormone balance, oral progesterone often works well and is more convenient. Your doctor will recommend the best route based on your specific needs.
https://www.oova.life/blog/progesterone-supplementation-guide
When should I start taking progesterone after ovulation?
Typically, progesterone supplementation for luteal phase support starts 2-3 days after ovulation (confirmed by LH surge or temperature rise). Your doctor will give you specific timing based on your protocol. Some women start immediately after a positive ovulation test.
https://www.oova.life/blog/progesterone-supplementation-guide
What's better: progesterone cream or pills?
Pills (oral micronized progesterone) are generally more effective and reliable than creams because absorption from creams is inconsistent. For medical conditions like fertility issues, low progesterone, or HRT, prescription pills or suppositories are strongly recommended over over-the-counter creams.
https://www.oova.life/blog/low-vs-high-progesterone-symptoms
How can I tell if I have low or high progesterone?
The only definitive way to know is through hormone testing via blood tests or at-home urine tests that measure progesterone metabolites. However, symptom patterns can provide clues: anxiety and irregular periods suggest low progesterone, while bloating and extreme fatigue suggest high progesterone.
https://www.oova.life/blog/low-vs-high-progesterone-symptoms
When during my cycle should I test progesterone levels?
Test progesterone levels during the luteal phase, typically 7 days after ovulation or around day 21 of a 28-day cycle. This is when progesterone should be at its peak, making it easier to identify if levels are too low or too high.
https://www.oova.life/blog/low-vs-high-progesterone-symptoms
What are the main differences between low and high progesterone symptoms?
Low progesterone typically causes irregular or heavy periods, anxiety, hot flashes, and sleep issues. High progesterone causes bloating, fatigue, intense breast tenderness, and depression-like mood changes. Low progesterone symptoms persist throughout your cycle, while high progesterone symptoms are most intense during the luteal phase.
https://www.oova.life/blog/low-vs-high-progesterone-symptoms
Can you have symptoms of both low and high progesterone?
Some symptoms like breast tenderness and mood changes can occur with both low and high progesterone, making it confusing. However, the timing, intensity, and accompanying symptoms differ. Hormone testing is the best way to determine which imbalance you're experiencing.
https://www.oova.life/blog/10-dpo
Can stress affect 10 DPO symptoms?
Yes, stress can worsen or mimic 10 DPO symptoms. Stress increases cortisol, which can cause cramping, fatigue, and mood changes similar to both PMS and early pregnancy. During the two-week wait, try stress-reduction techniques like gentle exercise, meditation, or spending time with loved ones.
https://www.oova.life/blog/10-dpo
Is it better to test at 10 DPO or wait?
It's better to wait until 12–14 DPO for more accurate results. Testing at 10 DPO often leads to false negatives because hCG levels may still be too low. If you absolutely can't wait, use a sensitive early detection test with first morning urine, and be prepared to retest in 2–3 days if negative.
https://www.oova.life/blog/10-dpo
What does implantation bleeding look like at 10 DPO?
Implantation bleeding at 10 DPO is typically light pink or brown, much lighter than a period, and lasts 1–2 days. It's often just spotting when you wipe or a few drops on a panty liner. However, only 15–20% of pregnant women experience implantation bleeding—most don't have any bleeding at all.
https://www.oova.life/blog/10-dpo
Why am I cramping at 10 DPO?
Cramping at 10 DPO can be caused by elevated progesterone (whether you're pregnant or not), implantation (if you're pregnant), or premenstrual cramping. Unfortunately, cramping alone can't tell you if you're pregnant since progesterone causes similar symptoms in both scenarios.
https://www.oova.life/blog/10-dpo
What are the chances of a BFP at 10 DPO?
If you're pregnant, you have about a 50–60% chance of getting a positive test at 10 DPO. This means there's a 40–50% chance of a false negative even if you conceived. Chances improve significantly by 12–14 DPO.
https://www.oova.life/blog/10-dpo
What DPO is most accurate for pregnancy testing?
14 DPO (the day of your missed period) is the most accurate time to test, with 99% accuracy. 12 DPO offers 80–90% accuracy. 10 DPO has only 50–60% accuracy. For best results, wait as long as you can—ideally until 12–14 DPO.
https://www.oova.life/blog/10-dpo
Is 10 DPO too early to test?
10 DPO is considered early for pregnancy testing. While some women get positives at 10 DPO, accuracy is only 50–60% if you're pregnant. For best results, wait until 12 DPO (80–90% accuracy) or 14 DPO/missed period (99% accuracy).
https://www.oova.life/blog/10-dpo
Can you have implantation at 10 DPO?
Yes, implantation can still occur at 10 DPO, though 84% of women have already implanted by this point. Late implantation at 10–12 DPO is normal. If implantation happens at 10 DPO, you won't get a positive pregnancy test for another 2–3 days.
https://www.oova.life/blog/10-dpo
What does a negative test at 10 DPO mean?
A negative test at 10 DPO does not mean you're not pregnant. It's very common to get negatives at 10 DPO even if you conceived. Your hCG levels may still be too low, or implantation may have occurred later. Wait until 12–14 DPO to retest for more accurate results.
https://www.oova.life/blog/10-dpo
Can you get a positive pregnancy test at 10 DPO?
Yes, but only about 50–60% of pregnant women will get a positive at 10 DPO. The other 40–50% have hCG levels that are still too low to detect. If you test negative at 10 DPO, wait 2–3 days and test again.
https://www.oova.life/blog/high-progesterone-symptoms
Can high progesterone cause weight gain?
Yes, elevated progesterone can cause temporary weight gain through water retention and bloating. This is a normal part of the luteal phase and early pregnancy.
https://www.oova.life/blog/how-to-increase-estrogen
Does stress affect estrogen levels?
Yes, chronic stress elevates cortisol, which can suppress estrogen production and disrupt hormonal balance. Stress reduction through meditation, yoga, adequate sleep, and self-care practices helps maintain optimal estrogen levels.
https://www.oova.life/blog/how-to-increase-estrogen
When should I consider medical treatment for low estrogen?
Consider medical intervention if natural methods don't improve symptoms after 3 months, if symptoms severely impact quality of life, if you're experiencing early menopause (before 40), or if you have fertility concerns. Hormone replacement therapy may be appropriate in these cases.
https://www.oova.life/blog/how-to-increase-estrogen
What are the signs that my estrogen is increasing?
Signs of rising estrogen include more regular menstrual cycles, reduced hot flashes, improved vaginal lubrication, better mood stability, increased energy, and improved skin elasticity. You may also notice reduced symptoms that originally indicated low estrogen.
https://www.oova.life/blog/how-to-increase-estrogen
Can exercise increase estrogen levels?
Yes, moderate exercise stimulates estrogen release and helps maintain hormonal balance. Aim for 150 minutes of moderate cardio weekly plus strength training twice per week. However, excessive exercise can actually lower estrogen, so balance is key.
https://www.oova.life/blog/how-to-increase-estrogen
How long does it take to increase estrogen naturally?
With consistent dietary and lifestyle changes, you may notice improvements in symptoms within 4-8 weeks. However, significant hormonal changes typically take 2-3 months. Tracking your cycle and symptoms can help you monitor progress.
https://www.oova.life/blog/how-to-increase-estrogen
What foods increase estrogen levels naturally?
Foods high in phytoestrogens can help increase estrogen naturally. The best options include flax seeds (high in lignans), soy products (tofu, tempeh, edamame), lentils, chickpeas, whole grains (oats, quinoa, brown rice), and garlic. These plant compounds mimic estrogen's effects in the body.
https://www.oova.life/blog/perimenopause
What helps relieve hot flashes quickly?
Cool environments, layered clothing, herbal teas, and medical treatments like gabapentin or HRT may help—depending on severity. Lifestyle changes like reducing caffeine and alcohol can also provide relief.
https://www.oova.life/blog/perimenopause
Are there tests to confirm perimenopause?
Yes. Tests measuring estradiol, LH, and FSH levels can indicate hormonal shifts—but diagnosis is often symptom-based since hormone levels fluctuate widely during perimenopause.
https://www.oova.life/blog/perimenopause
How do I know it's perimenopause and not something else?
A doctor may recommend hormone testing (like LH, E3G, and PdG) and track symptom timing. Diagnosis is often based on symptoms combined with age and menstrual pattern changes.
https://www.oova.life/blog/perimenopause
What's the earliest age perimenopause can start?
Some women begin experiencing symptoms as early as their mid-30s, though perimenopause typically starts between ages 38-45.
https://www.oova.life/blog/perimenopause
Does perimenopause affect mental clarity?
Yes. Brain fog and difficulty concentrating are common during hormone fluctuations in perimenopause.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
What happens after the last sign of perimenopause?
After your final period, you enter postmenopause. You'll need 12 consecutive months without a period to confirm menopause. Many symptoms gradually improve, though some like vaginal dryness may persist without treatment.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
When do perimenopause symptoms finally stop?
Some symptoms like brain fog improve after menopause, while others like hot flashes may continue for up to 10 years post-menopause. Vaginal symptoms often persist or worsen without treatment. Each person's timeline is different.
https://www.oova.life/blog/high-progesterone-symptoms
Is high progesterone a sign of pregnancy?
Yes, high progesterone is one of the earliest indicators of pregnancy. Progesterone levels rise significantly after conception to support the developing embryo and reach their peak during the third trimester.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
Can you still get pregnant in late perimenopause?
Yes, you can still get pregnant during perimenopause as long as you're having periods, even if they're infrequent. Continue using birth control until you've gone 12 consecutive months without a period and have officially reached menopause.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
Do symptoms get worse before perimenopause ends?
Yes, most perimenopause symptoms intensify in the final 1-2 years before menopause. Hot flashes peak around your final period, vaginal symptoms worsen, and mood changes increase. However, brain fog typically improves in late perimenopause.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
How long does late perimenopause last?
Late perimenopause typically lasts 1-3 years before your final period. However, the exact duration varies significantly from person to person. You've reached menopause after 12 consecutive months without a period.
https://www.oova.life/blog/high-progesterone-symptoms
What are the symptoms of high progesterone?
High progesterone symptoms include fatigue, bloating, breast tenderness, weight gain, anxiety, depression, headaches, and food cravings. During pregnancy, you may also experience increased nipple sensitivity and muscle aches.
https://www.oova.life/blog/TBD-10-symptoms-and-how-to-get-relief
What are the first signs that perimenopause is ending?
The earliest signs include longer gaps between periods (60+ days), intensifying hot flashes that peak around your final period, and worsening vaginal dryness. These symptoms typically increase in late perimenopause before you reach official menopause.
https://www.oova.life/blog/high-progesterone-symptoms
When should I be concerned about high progesterone?
Consult a healthcare provider if you experience high progesterone symptoms outside your luteal phase when not pregnant, or if symptoms include severe pelvic pain, abnormal vaginal bleeding, or rapid weight gain while on hormone therapy.
https://www.oova.life/blog/high-progesterone-symptoms
How do you test progesterone levels?
Progesterone can be measured through blood tests at your doctor's office or at-home urine tests that measure PdG (a progesterone metabolite). Testing is typically done during the luteal phase, about 7 days after ovulation.
