Fertilization doesn't always occur, even if you ovulateIf you ovulate and a sperm cell doesn't successfully fertilize the egg, the egg will simply move down the fallopian tube, through the uterus, and out through the vagina. You'll menstruate about two weeks later when the uterus lining is shed.

Answer 2

1. our body sheds the thick lining of the uterus, and your period starts.If one sperm does make its way into the fallopian tube and burrows into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in.

2. If fertilization does not occur, the endometrium, along with blood and mucus from the vagina and cervix make up the menstrual flow that leaves the body through the vagina during the period.
