It is possible to have a medication abortion if you are five weeks pregnant, because you should see the gestational sac during the vaginal ultrasound and you can have a medication abortion if you see the gestational sac. However, abortion is not possible because the gestational sac is too small and there is a risk that the abortion will be missed, which means that the gestational sac will not come out and the pregnancy may still be ongoing. The best time to have an abortion is between 40 and 60 days of pregnancy, when the damage to the patient’s body is the least, the bleeding is less, the operation time is shorter, and the incidence of incomplete abortion is the lowest. The incidence of incomplete abortion can reach 10%, and in case of incomplete abortion, the uterus needs to be scraped again, which will cause serious damage to the uterus.
