Ovulation Calculator

Are you trying to get pregnant or planning on it in the near future? If so, you can greatly improve the likelihood of getting pregnant by determining when you will ovulate next. Ovulation is the release of a female's ripe egg from her ovary. When this occurs, you are the most fertile.

Use our Ovulation Calculator to estimate your next ovulation date; simply enter the first day of your last menstrual period and the average length of your cycle. Because our tool provides you with only an estimate, consider yourself the most fertile during the period of 3 days before and 3 days after the estimated ovulation date. Best of luck!!

    i had a kind of app on my phone that tracks monthly period, fertility and ovulation. i never got to used it again after giving birth. Maybe I should start tracking things again as part of family planning.

    This ovulation calculator works cos the time it gives me for my ovulation comes within that week. At least it helps me to be in check.

    Don’t agree with the ovulation calendar at all. I know for sure the date my first child was conceived, and it was 11 days from the start of my period, not 20! My cycle is about 34 days long. I’ve used 11 days to happily conceive 5 more children for my husband of 17 years. Don’t put your faith in this calendar!
