In principle, a drug abortion can only be performed one month after a normal menstrual period and three days after it is clean. Because it takes time for the uterus to recover, if you have intercourse too early, it will cause uterine excitement and a small amount of endometrial shedding, which may cause a small amount of bleeding and may even cause abdominal pain and high fever, which may cause tubitis, endometritis and cervicitis. As each person’s constitution is different, there is not a 100% chance of this manifestation, but a 10%-20% chance. If there are no such manifestations, it is advisable to observe. When having intercourse, it is important to use good contraception so as not to cause another pregnancy. Premature intercourse can cause pre-eclampsia or even habitual abortion, which can affect future pregnancies.
