When a woman is pregnant for one month and wants to have an abortion due to fetal or maternal factors, she can first choose to have a medical abortion or an abortion. The drug abortion is suitable for the early stage of pregnancy, that is, within 7 weeks of pregnancy, because the development of the placenta is not very mature at this time, so the connection between the fetus and the mother is relatively not close, and it is easy to separate the placenta from the endometrium by choosing the drug abortion at this time, so the drug abortion is also relatively easy. Mifepristone causes the meconium to degenerate and necrosis, separating from the endometrium and softening the cervix, while misoprostol causes the uterus to contract, leading to the expulsion of the embryo and ultimately to abortion. Abortion is also an option in the first trimester, mainly for women who have had an incomplete medical abortion, or who do not want to opt for a medical abortion for fear of incompleteness. An abortion is simply the scraping of the endometrium, which is often referred to as a curettage. The fertilized egg is formed and laid in the endometrium, so the scraping of the endometrium is one of the methods to terminate the pregnancy, and the gestational sac is scraped out after the endometrium is removed, so the pregnancy is terminated.
