That's why we talk about three types of menstrual cycles:
- Normal cycle : when it lasts 28 days and ovulation occurs between day 14 and 15 of the cycle.
- Short cycle: those women who have a menstrual cycle shorter than 25 days. In these cases, ovulation is closer to the period, as it takes place on approximately day 11.
- Long cycle: if it lasts longer than 28 days, so ovulation takes place later.
