How to Know If You’ve Ovulated with PCOS
Published September 6, 2025
If you have Polycystic Ovary Syndrome (PCOS), knowing if you’ve ovulated can feel like trying to solve a mystery. Your cycles might be irregular, or you might not see the usual signs of ovulation that many people rely on. This can be frustrating, especially when you're trying to seriously track your fertility or avoid pregnancy without relying on hormonal birth control. But don’t worry, you can know if you’ve ovulated with PCOS. It just takes a little extra insight, the right tools, and patience!
Let’s walk through how you can figure out if you’ve ovulated, even when PCOS is part of your equation.
Understand What Ovulation Looks Like
Our first step is a better understanding of what ovulation typically looks like. It happens when your ovary releases an egg, making it available for fertilization. This natural process usually occurs at around the middle point of your cycle.
Typically, ovulation will cause a few key changes in your body that can be tracked:
Cervical Mucus (CM): Right before ovulation, your CM will begin to change. It gets thinner, more slippery, and sometimes stretchy (think egg whites). This is a sign that your body is preparing itself to allow sperm to swim to the egg.
Basal Body Temperature (BBT): After ovulation happens, your body’s internal temperature will rise and stay elevated for the rest of your cycle, a sign that a hormone called progesterone has been released to support a potential pregnancy.
LH Surge: An LH surge is a spike in the luteinizing hormone (LH) that happens just before ovulation. Ovulation predictor kits (OPKs) can be used to test for this surge, but women with PCOS may see false positives, making this tool trickier to rely on.
With PCOS, your cycles may not be so regular and predictable. Since you may not see these same signs every month, it’s important to know what tools you can rely on. This is where charting your body’s internal temperature (BBT) can really help to clear things up.
Track Your BBT for Clear Signs of Ovulation
Tracking your basal Body Temperature (BBT) with Tempdrop is one easy way to help you confirm ovulation, especially with PCOS. When ovulation occurs, your body reliably releases progesterone, causing your internal temperature to rise. This temperature spike stays elevated for the rest of your cycle if you’ve ovulated.
Why BBT is Important for PCOS: BBT tracking is consistent and objective. When you see that internal temperature shift, you’ll have concrete proof that ovulation has occurred, alongside the other signs that may fluctuate throughout your cycle (like Cervical Mucus and LH tests).
How to Read Your BBT Chart: A sustained temperature rise of at least 3 days in a row is a strong indicator you’ve ovulated. Your temperature should stay elevated until you either get your period (if pregnancy hasn’t occurred) or a pregnancy test confirms otherwise. This is the sign that you want to look for!

Look for a Sustained Temperature Rise
Once your Tempdrop BBT chart shows you that temperature spike, you’ll need to look for at least three consecutive days of elevated temperatures with a coverline (the red line across the Tempdrop chart). If you don’t see this sustained rise or a coverline, ovulation may not have occurred yet.
It’s also important to remember that ovulation can be delayed or irregular with PCOS, so you might not see a rise until much later in your cycle than you would think. This is why tracking your BBT for a few cycles is incredibly useful. Over time, you’ll start to see patterns emerge and you’ll have a clearer sense of when ovulation will typically happen for you, even if it goes against the norm.
Track Your Cervical Mucus
While BBT is great for confirming ovulation after it’s happened, tracking cervical mucus (CM) can help you pinpoint your fertile window and trust what you’re seeing with your temperatures. In the days leading up to ovulation, your cervical mucus will change in texture and quantity.
With PCOS, your mucus patterns may be a little different, but you can still look for the typical signs:
At Ovulation: You’ll notice that your CM becomes clear, slippery, and stretchy, resembling egg whites. You may feel a slippery sensation and see no mucus.
By tracking both your BBT and CM, you get a fuller picture of what your cycle’s indicators look like. The combination of these two signs can help you pinpoint when ovulation is most likely happening for you, even if you feel like your cycle length is too unpredictable.
Be Patient And Don’t Stress!
If you have PCOS, you might be testing for ovulation with OPKs and not seeing a clear positive result every month. That’s totally normal! In fact, many people with PCOS can experience false positive results or no surge at all, even when they do ovulate. So don’t get discouraged if you miss a surge, or don’t get a definitive result on an OPK.
The key with PCOS is to keep tracking. The more data you collect, the better you’ll understand your body!
If you haven’t ovulated yet, keep charting!
If you haven’t experienced a sustained rise in temperature along with a change in your cervical mucus, you probably haven’t ovulated yet. If it’s past day 21, then you know that your ovulation is delayed. Keep charting and tracking your data so that when you do ovulate, you can be confident in your fertility signs.
Final Thoughts: You Can Know If You’ve Ovulated with PCOS!
Tracking ovulation with PCOS is totally doable. All you need are the right tools, patience, and a little extra insight. By charting your BBT, monitoring your cervical mucus, and tracking your cycles over time, you’ll gain a much clearer understanding of what’s happening in your body, whether you're trying to conceive or just trying to understand yourself better.
You may not have textbook, regular cycles that other women experience. But with consistency, you’ll get closer to understanding your own unique rhythm, and that’s empowering. Keep at it, and remember, you’ve got this!
