Ovulation Calculator & Fertile Window: What Couples Actually Ask

Important disclaimer

Fertility and ovulation tools are **educational only**. They are not contraception, not a fertility diagnosis, and not a substitute for reproductive healthcare.

Why this stays trending

Trying-to-conceive communities constantly discuss fertile windows, LH tests, and irregular cycles. A simple calculator helps orientation—especially when you want privacy without another app login.

Limits to remember

- Irregular cycles change the window - Stress, illness, and PCOS can shift timing - Confirm plans with a clinician when needed
