👩‍💻Fertility apps can be helpful

👉🏻But they’re predicting ovulation, not confirming it.

👉🏻Most apps use averages and algorithms based on cycle length, which means they can easily get your fertile window wrong if:

• you ovulate earlier or later
• your cycle changes month to month
• stressed
• coming off contraception
• or dealing with hormone imbalances

And this matters more than most women realise 👀

🕵️‍♀️ Because even progesterone blood tests are often timed using these predicted ovulation dates

👉🏻So if ovulation happened later than the app assumed, a day 21 progesterone test can be done too early and miss what’s actually happening hormonally

This is why I always encourage women to learn THEIR body:

✨ cervical mucus
✨ basal body temperature
✨ ovulation tests
✨ symptoms + cycle patterns

Because your hormones don’t run on an app’s schedule.
