The best time for a medication abortion is usually between 40 and 45 days of pregnancy.
Medication abortion, also known as medication abortion, generally refers to an early termination of pregnancy by softening the metaplasia of the uterus and cervix through the administration of mifepristone tablets and misoprostol, and then expelling the embryo through the vagina through uterine contractions.
There is a requirement for the timing of the application of medication abortion, which is usually chosen to be used between 35 and 49 days after pregnancy. After 35 days of pregnancy, the gestational sac begins to appear in the uterus and the size of the embryo can be monitored by ultrasound. The embryo and its appendages become smaller on the 49th day of pregnancy, which is the most appropriate stage for medication abortion.
Once the pregnancy exceeds 49 days, the fetus develops rapidly and the gestational sac and its appendages continue to grow and develop. It is difficult to completely expel the gestational sac from the uterine cavity with a medication abortion, and the risks of bleeding and other risks to the pregnant woman are greatly increased. If incomplete abortion and bleeding occur over a long period of time and are not treated in time, it will lead to complications such as anemia, secondary infections or uterine adhesions, which will also have a certain impact on future pregnancies.
When patients undergo medication abortion in the clinic, they need to be guided by a doctor to avoid causing adverse effects.
