The painless abortion procedure requires that the patient’s pregnancy be performed within 70 days of pregnancy, inclusive of the 70th day of pregnancy. If a woman is 70 days pregnant and an ultrasound is done to show that the gestational sac matches the size of 70 days of menopause, the painless abortion procedure can be performed in this case. If a woman has 70 days of menopause, but doing an ultrasound shows that the embryo is larger than 70 days, it is mainly related to the woman’s early ovulation, early pregnancy, or wrong projection method, in this case, there is no way to do painless abortion surgery. Painless abortion on the 70th day of pregnancy has a larger gestational sac, so the damage to the cervix and uterus during the procedure is greater. It is recommended to use misoprostol in the vagina or anus before the painless abortion procedure, which can soften the cervix and reduce the damage to the uterus and cervix during the procedure.
