Ovulation is the part of the menstrual cycle when the ovary releases a mature egg through the fallopian tube into the uterus, making it available for fertilization. Hormonal changes play a massive role in the process of ovulation and trigger many observable effects. Tracking these changes makes it possible to determine exactly when ovulation begins, which many women use to either increase or decrease their chances of getting pregnant.


1. When Does It Happen

Most menstrual cycles last between 28 and 32 days. Ovulation typically occurs about midway through the menstrual cycle. While there is significant variation between each person, most people can predict ovulation by counting about 14 days from their last menstrual period. The days surrounding ovulation, 10 through 18, are the most fertile phase.
