Why it matters more than you might think and how to tell if your body’s really doing it.
I think I can speak for most '90s girls when I say we were never really taught how to read our cycles. And even more of us weren’t taught that ovulation, not just menstruation, is one of the most important reflections of overall health.
Ovulation is how your body makes progesterone, the hormone that steadies your mood, helps you sleep deeply, protects your heart, and supports bone strength. When ovulation happens regularly, it’s a quiet but powerful sign that your brain, ovaries, and hormones are communicating beautifully.
When it doesn’t, things feel off. Cycles get unpredictable. PMS hits harder. Sleep feels lighter. Anxiety creeps in. And even if your period still shows up, it doesn’t always mean ovulation did.
The encouraging part is that your body leaves clues — gentle signals that tell you when ovulation is on track and when it might need some support. Once you know how to read them, you gain incredible insight into your health.
Why Ovulation Matters
Each month, estrogen takes the lead in the first half of your cycle, helping follicles grow and preparing the body for ovulation. After an egg is released, progesterone steps in and shifts everything to a calmer, more restorative state. That rhythm — estrogen, then progesterone — is what keeps your hormones in harmony.
Progesterone does much more than prepare the uterus for pregnancy.
It also:
Calms your nervous system by supporting GABA — your brain’s natural “chill” neurotransmitter.
Promotes deeper, more restorative sleep.
Balances estrogen to ease PMS, mood changes, and breast tenderness.
Supports bone strength and healthy circulation, complementing estrogen’s protective effects.
Helps stabilize thyroid and blood sugar balance for steadier energy and mood.
When ovulation doesn’t occur, progesterone isn’t produced, since it’s made only after the egg is released. Without that balancing effect, estrogen becomes relatively unopposed, which can lead to symptoms like heavier or more painful periods, breast tenderness, irritability, restless sleep, or simply feeling “off” hormonally.
How to Tell If You’re Ovulating
Bleeding doesn’t always equal ovulation. You can have a cycle without releasing an egg, especially during times of stress, sickness, thyroid imbalance, or perimenopause. But your body always tries to communicate what’s happening, and the signs are there if you pay attention.
1. Cervical Mucus Changes
In the days leading up to ovulation, rising estrogen makes cervical mucus clear, slippery, and stretchy (think egg whites). This type of mucus helps sperm reach the egg and signals that ovulation is near.
After ovulation, progesterone thickens it, and it becomes cloudy or dry. Tracking these changes over a few cycles can help you learn your unique rhythm — no apps required, just awareness.
2. Basal Body Temperature
Progesterone slightly raises your resting body temperature after ovulation — usually by about half to one degree Fahrenheit — but it’s a measurable shift.
If you take your temperature each morning before getting out of bed, using a thermometer that reads to two decimal places, you’ll notice a small but consistent rise once ovulation has occurred.
This temperature change isn’t used to predict ovulation, but rather to confirm that it has already happened. Over time, you’ll start to recognize your own unique pattern — and how it aligns with changes in your energy, sleep, and mood throughout your cycle.
When combined with cervical mucus observations, basal body temperature (BBT) tracking becomes a powerful tool for understanding your fertile window. Mucus changes signal when fertility is beginning and approaching its peak, while the temperature shift confirms when ovulation has passed. Together, they can help you identify your fertile days — whether you’re trying to conceive, avoid pregnancy naturally, or simply understand your body more deeply.
3. Hormone Tracking and Femtech Tools
Cycle-tracking tech can be a helpful companion if you prefer data over daily notes. Modern devices now measure small changes in temperature, heart rate, or urinary hormones to estimate when ovulation is occurring.
Choose tools that reflect your body’s signals rather than relying on generic calendar predictions. If you’d like to explore the best options, I share more about this in my post on Femtech and Cycle Tracking.
4. The 7-Day Post-Ovulation Progesterone Blood Test
This is the classic “day 21” test — though it’s not always day 21. It should be timed for about seven days after you believe ovulation occurred.
A progesterone level above about 3-5 ng/mL typically confirms that ovulation occurred. For optimal fertility and luteal-phase support, many clinicians look for levels above 15 ng/mL, and in some fertility circles, above 19 ng/mL is considered ideal. If levels are lower, it may suggest that ovulation didn’t occur in that cycle or that progesterone production was on the lower end. Tracking a few cycles with this test can help clarify your individual hormonal pattern over time.
5. Urinary Hormone Testing
At-home urine tests can also help confirm ovulation by measuring surges in luteinizing hormone (LH) before ovulation and progesterone metabolites (like pregnanediol-3-glucuronide, or PdG) afterward. These tests offer a clear picture of your hormonal rhythm across the month — a great complement to temperature or mucus tracking if you want more precision.
Companies such as Proov, Mira, and Inito provide reliable at-home options for tracking LH and PdG, allowing you to visualize both the rise and fall of your hormones throughout the cycle. Some even sync with apps to chart your fertile window and luteal phase trends over time.
When Ovulation Is Off Track
If you’ve noticed longer or shorter cycles, low progesterone, or no clear mucus or temperature pattern, ovulation may be inconsistent or missing altogether. It’s common, especially in modern life, but it’s also a signal worth listening to.
Some of the most common reasons include:
Ongoing stress or high cortisol
Undereating or over-exercising
Thyroid imbalances
PCOS or insulin resistance
Perimenopause
Hormonal contraceptives (especially after discontinuing use)
Restoring ovulation is less about chasing a perfect cycle and more about giving your body what it needs to feel safe and nourished. Stable blood sugar, enough calories and protein, restorative sleep, and nervous system support are all part of the foundation.
The Role of Progesterone
Progesterone is the quiet hero of hormonal balance. When it’s present, you often don’t notice. You simply feel grounded, clear, and resilient. But when it’s low, you feel it everywhere: anxious thoughts, lighter sleep, heavier bleeding or absent cycles, or mood changes that feel disproportionate to what’s happening around you.
Healthy progesterone levels:
Help you handle stress with more ease
Balance estrogen to prevent excess stimulation
Support bone and heart health
Promote calm focus and more restorative sleep
Because progesterone is only made after ovulation, regular ovulation is what keeps these benefits flowing. It’s not about “perfect cycles” — it’s about the ongoing conversation between your hormones and your well-being.
Reclaim the Rhythm of Your Cycle
Ovulation is far more than a fertility event. It’s a reflection of your body’s inner harmony — the rhythm between your brain, ovaries, and hormones that keeps everything else in balance. Each ovulatory cycle brings a rise in progesterone, the hormone that helps you sleep deeply, think clearly, and feel emotionally steady while supporting your heart, bones, and metabolism.
If you’re unsure whether you’re ovulating regularly or if your cycles feel unpredictable, your PMS is intensifying, or your energy just isn’t what it used to be, it’s worth exploring what’s happening beneath the surface. Restoring ovulation isn’t only about conception; it’s about restoring rhythm, balance, and vitality.
