It can be helpful to maintain a menstrual calendar to determine how regular your periods are. The first day of the menstrual cycle is the day that bleeding starts, and it ends the day that bleeding starts again. Menstrual cycles vary between women however, and a person without a 28-day menstrual cycle may need to track their menstrual cycle to more accurately determine when ovulation might occur. Since day 10-18 of the menstrual cycle is typically the most fertile phase of the menstrual cycle, women with regular cycles can fairly easily determine when they are ovulating and most likely to conceive.

Many people would like to predict their ovulation date, mostly to increase their chances of getting pregnant. Otherwise, menstruation occurs, and blood and mucosal tissue from the inner lining of the uterus is expelled. If fertilized, the egg will implant in the uterus 6-12 days later.

This is important when trying to conceive because fertilization of the egg can only occur for 12-24 hours after release during part of the luteal phase, when a mature egg travels through the fallopian tubes towards the uterus. On average, ovulation occurs within the 4 days before or after the midpoint of a woman's menstrual cycle (14 days before the start of a woman's next menstrual period).ĭay 10-18 of the menstrual cycle (on average) is the most fertile phase of the menstrual cycle.
