Women with reduced menstrual flow in the second month after miscarriage is not necessarily a problem with the endometrium or the uterine cavity, as follows: First, if the ultrasound results of the post-miscarriage review are all normal, there is no residual, and the menstrual flow is normal in the first month after the miscarriage, and reduced menstrual flow in the second month, do not be overly nervous. In some cases, women start to take short-acting contraceptives on the day of abortion, such as Yosmin, Yosiyue and other drugs, then it will inhibit the growth of the uterine lining and reduce the amount of menstruation, so the decrease in the amount of menstruation during the contraceptive pill is a normal phenomenon. Second, if you have never taken a short-acting contraceptive pill after abortion, the decrease in the second month is not a big problem. Because abortion is traumatic to the uterine lining, it may take 3-6 months or even longer if the uterine lining is to fully recover. Third, there are very few women who may damage the endometrium more seriously, and even lead to scarring and adhesions, at this time may lead to a decrease in menstrual flow, and more than six months are likely to become less and less, can be diagnosed by three-dimensional reconstruction ultrasound or hysteroscopy to confirm the diagnosis.
