About the Conception Calculator

This tool estimates ovulation and fertile days using your menstrual cycle length. It helps identify days with a higher chance of conception.

How It Works

Ovulation usually occurs about 14 days before the next period. The fertile window includes the ovulation day and the 5 days before it.

Important Information

Results are estimates only. Ovulation can vary due to stress, illness, or hormonal changes. This calculator should not be used as medical or contraceptive advice.

Advice

For better accuracy, track cycles over several months. If you are trying to conceive or have concerns about fertility, consult a healthcare professional.

FAQs

Can cycles vary? Yes, cycle length may change month to month.
