If you have a regular menstrual cycle*, use our ovulation calendar to help you figure out when you ovulate so you know when to have sex to try to get pregnant.
Once you have results,
Your menstrual cycle length can help us predict when you’re likely to get your next period and ovulate. The menstrual cycle is the process of your ovaries releasing an egg every month.
To find out how long your menstrual cycle is, count from the first day of your last period up to the first day of your next period. The typical menstrual cycle is 28 days long, but each woman is different. Your menstrual cycle length may be different from month to month.
Your cycle length is 28 days. Click on any day in the calendar below to add a note. Use notes to record when you have unprotected sex, when your period starts on an unexpected day and track your basal body temperature (BBT).
* If your cycle is or becomes irregular, you should not use this calendar.
