1. If you are pregnant for too long, do painless abortion. Because the days of pregnancy are too long, the gestational sac is already relatively large, and there will be relatively more bleeding, which is also very harmful to the body. Painless abortion within 35-70 days of pregnancy will make the operation safer and simpler, and the recovery time of women after painless abortion will be shorter.

2. The pregnancy time of painless induced abortion is too short, because the embryo has just begun to develop, and it is still very small, which is prone to empty aspiration or missed aspiration, which will lead to the failure of the operation and the possibility of incomplete abortion, so it is necessary to carry out a second palace cleaning.

3. If the pregnancy time exceeds 100 days, induced labor operation is needed at this time, which will increase the pain of pregnant women and the risk of operation. However, if fetal dysplasia is found after hospital examination, painless abortion can also be done.
