A Honor Society of Nursing (STTI) answered. Ovulation usually takes place about halfway through a normal 28-day menstrual cycle. After ovulation, the body produces high levels of the hormones progesterone and estrogen. The hormones thicken the lining of the uterus in anticipation of a fertilized egg. If no fertilization occurs after ovulation, after about 14 days the lining of the uterus is shed to begin menstruation.
