Childbearing, healthy women with a history of sexual life, usually regular menstrual cycles, once the menstrual period should be considered pregnant. If you are pregnant and don’t want it, you can go to the hospital for ultrasound examination after menopause for more than 35 days, and the pregnancy sac can usually be seen in the uterus at this time. Ultrasound in the uterine cavity can see obvious pregnancy sac when if you do not want to decide to abort. If the gestational sac is not obvious, you can review the ultrasound at 6 weeks of pregnancy, generally 6 weeks of pregnancy can see the embryonic buds and the primitive heart tube pulsation, at this time you can choose to abort, generally not more than 7 weeks. If the abortion month is large, the uterus enlarges significantly, abortion on the uterus damage increases. If the pregnancy is more than 7 weeks, you can only choose artificial abortion, artificial abortion on the human body damage is relatively large. If the pregnancy is less than 7 weeks, you can choose medication abortion, and medication abortion is relatively less damaging to the human body.
