The first time after the abortion, the menstrual flow is low, it is best to check the ultrasound after the menstruation is clean, to determine whether there are adhesions in the endometrium. If there are adhesions, hysteroscopic treatment is necessary; if there are no adhesions, you can try to take some Chinese medicine to relieve the problem, such as Wuji Baifeng Pill will help to some extent. If the result is not good, you have to check the ultrasound a week before your period to measure the thickness of the endometrium. If the endometrial thickness is less than 8mm, it means the endometrial lining is not growing well and some hormonal drugs are needed to promote the growth of endometrial lining to increase menstrual flow. The clinical treatment is usually a combination of GlaxoSmithKline and progesterone. You must not miss any dose during the medication period and eat less cold and stimulating food.
