The first is to take a pill to get the embryonic tissue out of the uterine cavity. There are two kinds of pill for abortion, one is called mifepristone and the other is called misoprostol. The time to take the medicine is 3 days, 1-2 days to take mifepristone, the third day to take misoprostol, only after misoprostol eaten, embryonic tissue may flow out of the uterine cavity. The length of time it takes to flow out is entirely related to the patient’s sensitivity to the drug, and the size of the embryo. Some people are more sensitive to the drug, and the tissue will flow out half an hour after taking misoprostol. Some people are not very sensitive to the drug and may not be able to flow out for 4-5 hours after taking it, at which point the patient needs to be treated accordingly.
