It is relatively appropriate to perform abortion within one and a half to two months of pregnancy, because the size of the gestational sac is relatively moderate during this period and it is not easy to have a missed suction. In addition, the damage to the woman’s uterine lining is also relatively small, so it is better to choose this period for abortion if the pregnancy is terminated. Before having an abortion, women should undergo routine preoperative checkups, such as ultrasound examination to understand the size of the gestational sac and the location of the implantation, and routine leucorrhoea examination to understand whether there is vaginal inflammation. If there is vaginitis, it is more appropriate to treat it in time before performing the abortion to avoid the inflammation from infecting the woman’s body. In addition, routine blood tests and tests for infectious diseases should be performed. If the tests are not contraindicated, abortion can be chosen to terminate the pregnancy.
