Painless abortion can be done in the second month of pregnancy. Painless abortion refers to abortion performed under intravenous anesthesia, which is the addition of intravenous general anesthesia on top of suction abortion surgery, so that the patient does not feel any pain during the procedure. The required number of days of menopause for an abortion is 7-10 weeks, but an ultrasound is also needed to determine the size of the gestational sac during an abortion. If the menopause is too short and the embryo is too small, it is easy to miss suction during the abortion. If the time of menopause is too long, after developing into a fetus, suction will not be able to eliminate the fetus. Therefore, in the second month of pregnancy, you need to do ultrasound first. As long as it has not developed into a fetus, you can have a painless abortion.
