Understanding Your Cycle
Average cycle length: A typical menstrual cycle is 21–35 days, with 28 days being the average.
Fertile window: You're most likely to conceive during the 5 days before ovulation and the day of ovulation itself.
Ovulation: Usually occurs about 14 days before your next period starts, regardless of cycle length.
This tool provides estimates based on your logged data. For medical advice, please consult your GP or a fertility specialist.
