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 taking short-acting contraceptives on the day of miscarriage, 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, a very small number of women may damage the endometrium more seriously, or even lead to scarring, adhesions, at this time may lead to a decrease in menstrual flow, and more than six months may become less and less, you can confirm the diagnosis through the three-dimensional reconstruction ultrasound or hysteroscopy.
