Use the ovulation calculator to help improve your chances of getting pregnant and browse the articles on our website to get other expert advice on the best ways to get pregnant. Menstrual periods are different for each woman and also differ from month to month.
To increase your chances of getting pregnant, our interactive ovulation calculator will help you forecast your fertility in a simple calendar format. Just select the first day of your last period in the calendar below, and how long your cycle usually lasts (typically between 20 to 45 days). Find out which days you're most likely to conceive.
NOTE: If your menstrual cycles tend to be irregular, you may have trouble pinpointing your ovulation day based on this calendar alone, and you may then need to use an ovulation predictor kit.
