BaiBoo's Ovulation Calendar helps you to estimate when you are most likely to be fertile so that you can get pregnant. We will display the key dates, indicating the highest probability to get pregnant. Just enter the first day of your last menstrual period and then press 'View Calendar' to display your personal ovulation calendar.

If you know the length of your menstrual cycle and/or of your luteal phase you can enter this also; it will help predict your fertile period with more accuracy. The average menstrual cycle is 28 days and the average luteal phase is 14 days.

* Please note that the Ovulation Calendar is aimed at helping you to get pregnant. It is not a tool to prevent pregnancy. The more regular your menstrual cycles are, the more accurate the Ovulation Calendar will be.
