The reason is that two medical abortions can affect subsequent pregnancies because they tend to prolong the bleeding time of the endometrium and increase the chance of local infection, which can lead to endometritis, pelvic inflammatory disease and tubal inflammation. When local inflammation occurs, it will easily cause local endometrial adhesions or tubal obstruction, which will affect pregnancy. If the endometrium is repeatedly scraped, it may even cause endometrial adhesions, which may affect the fertilized egg’s implantation in the endometrium and lead to habitual abortion or infertility. Therefore, when women do not want to have children, they must do a good job of contraception to avoid multiple abortions.
