How Does the Fertility Calculator Work?
The calculator uses:
- First day of your last menstrual period (LMP)

Ovulation generally occurs around 14 days before your next period. The fertile window usually includes the 5 days before ovulation and the day of ovulation itself.
The Fertility Calculator estimates:
- Ovulation date
- Fertile window
- Best days to conceive
- Next expected period date
Why Track Your Fertile Window?
Tracking fertility can help:

Tracking these symptoms along with a Fertility Calculator may improve ovulation prediction accuracy.
