In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before the start of the next menstrual period. However, each person's cycle length may be different, and the time between ovulation and the start of the next menstrual period may vary.
Between days six and 14 of your menstrual cycle, FSH causes follicles (small sacs of fluid in your ovaries that contain a developing egg) in one ovary to begin to mature. During days 10 to 14 of the cycle, only one of the developing follicles forms a fully mature egg. Around day 14 in the menstrual cycle, a sudden surge in LH causes the ovary to release this egg. This is ovulation. After ovulation, the hormone progesterone rises which helps prepare your uterus for pregnancy.
At what day is the egg released?
