Abortion includes medication abortion and artificial abortion, of which the best time for medication abortion is intrauterine pregnancy within 49 days of menopause, and the best time for artificial abortion is intrauterine pregnancy of 6 to 10 weeks, not later than 12 weeks. Medication abortion refers to the method of terminating early pregnancy by taking Mifepristone tablets and Misoprostol tablets, which is applicable to pregnancy within 49 days of menopause, when the gestational sac is small, and the use of medication is able to promote uterine contraction, so as to discharge the pregnancy tissue. The best time to perform an abortion is when the pregnancy is around 6 to 10 weeks old, when the embryo is more visible and not too large, and the surgical operation can remove the embryo intact. If it is more than 10 weeks and not more than 12 weeks, the operation can also be taken. If it is more than 12 weeks, the embryo needs to be induced due to its relatively large size.
