One of the most important things to understand when you’re trying to conceive is when you ovulate.
And no, it’s not necessarily the day your app tells you.
knowing when you ovulate helps you understand:
- When your fertile window is (the time in your cycle you can fall pregnant)
- Whether you’re ovulating regularly.
- When to test progesterone (This needs to be tested after ovulation has occurred)
- How long your luteal phase is: The time between ovulation and your period. A short luteal phase can result in low progesterone which leads to fertility issues.
Period tracking apps can be really useful for helping you understand your cycle and identifying patterns over time but your app doesn’t actually know when you ovulate. It makes a prediction based on your previous cycle data. And because ovulation can shift from cycle to cycle, that prediction may not always be accurate.
Although you can only fall pregnant the day of ovulation (24 hours) sperm can survive in the productive track for up to 5 days meaning you have 5-6 days of the month when you can fall pregnant (fertile window).
Your chances of conceiving are at the highest 1-2 days before ovulation so understanding when you are about to ovulate is just as important as understanding when you have ovulated.
Signs of ovulation
- Cervical mucus - this is one of the most useful signs that ovulation is approaching (or already happening) fertile cervical mucus will be similar to raw egg white and be slippery, clear and stretchy. Sometime it is so slippery it may just be a wet patch in your underwear.
- Ovulation predictor kits (OPKs) - detect the LH surge, which usually happens before ovulation. A positive OPK can help you identify that ovulation is likely approaching, but it doesn’t confirm that ovulation actually happened.
- Basal body temperature (BBT) - After ovulation, progesterone rises and causes a small increase in your resting body temperature. By tracking your BBT over time, you can look for a sustained temperature rise, which can help confirm that ovulation has occurred.
- Mid-cycle changes - Some people notice other signs around ovulation, such as:
- Pelvic pain or cramping
- Increased libido
- Breast tenderness
- Changes in mood or energy
These can be useful clues, but they’re not reliable on their own for confirming ovulation.
If you’re not sure when you ovulate, start by tracking your cervical mucus and looking at your cycle patterns.
