If there is occasional bleeding after menstruation, there is usually no need to pay special attention to it. If there is a small amount of bleeding after menstruation, you should seek medical treatment as follows: 1. For women of childbearing age, if there is a small amount of bleeding after menstruation and you have been infertile for many years, you should check your endocrine secretion and ovulation status. Because menstruation is clean and there is a small amount of bleeding, usually still endocrine problems. A sudden drop in estrogen can’t support the endothelium, which causes it to fall off, resulting in bleeding. With endocrine problems, there will be corresponding problems with ovulation, and there is no way to ovulate normally. Therefore, for couples of childbearing age and with fertility requirements, it is necessary to check the endocrine and do ultrasound to monitor ovulation. On the one hand, it is to treat the problem of small amount of bleeding after menstruation is clean, and on the other hand, it is also to treat the problem of infertility; 2. For patients who do not have the requirement of reproduction but still have small amount of bleeding after menstruation is clean, endocrine examination should be carried out, and the problems found in the endocrine examination should be given treatment in time. The treatment is generally estrogen-progestogen therapy, to supplement small doses of estrogen to support the endothelium, so that the endothelium does not fall off and cause bleeding, so it is necessary to give estrogen-progestogen sequential therapy, as well as estrogen-progestogen combination therapy and so on.
