The uterus contracts under the influence of prostaglandin, the production of which increases. But the level of estrogens and gestagens at this time is significantly reduced. As a result, with menstrual bleeding comes out the detached layer of endometrium. Nothing unusual woman in this week does not experience, menstrual short-term pain in the lower abdomen, discharge from the vagina for a period of 3 to 7 days.
