The Ovulation Calculator / Ovulation Calendar helps women in family planning by predicting the exact time of ovulation. This information is vital to avoid unwanted pregnancies. Ovulation occurs only on one day in the menstrual cycle of a woman followed by menstruation after 2 weeks. However, ovulation time from the start of the menstrual cycle can vary.
An ovulation calendar or an ovulation calculator is most useful for women whose menstrual cycles are regular. The calculator works by simply entering the first day of your last menstrual period and the length of that cycle.
Once this information is entered the ovulation calculator will show your approximate day of ovulation and the days when you are likely to get pregnant. Good Luck!!
