Abortion in early pregnancy is usually performed through medication or induced abortion to terminate the pregnancy. Both medical and induced abortions can affect the lining of the uterus. First of all, it can cause longer bleeding, infection or anemia, pelvic inflammatory disease and cervical inflammatory disease. For example, when abortion is performed, the endometrium is partially cleared and there are certain complications after cleansing, which can cause cervical adhesions, uterine cavity adhesions, menstrual irregularities, and even pelvic inflammatory disease. In some women, adhesions to the fallopian tubes after miscarriage may affect future pregnancies and may lead to ectopic pregnancy in the next pregnancy. Therefore, after miscarriage, it is important to actively review the ultrasound to ensure that the uterine cavity is normal. If necessary, oral medication can be taken to repair the lining to avoid the chance of infertility.
