Female peritoneum glands {ovary, gland} can make female hormones and eggs. The 28-day female-hormone menstrual cycle has high estrogen for 21 days and high progesterone for 7 days, with estrogen increasing until day 12 after menstruation and then progesterone increasing until day 21. Egg ovulation is at day 14, when luteinizing hormone and follicle stimulating hormone peak.
