The medication abortion is for the termination of pregnancy within 49 days, because the gestational sac is relatively small at this time, generally by taking the medication, the gestational sac and the meconium can be expelled from the uterus naturally, and the impact on the cervix, vagina and vulva, is not very obvious. This means that the doctor will not know if you don’t tell him or her, and you can hide it because it does not have a very obvious effect on the next pregnancy and the birth of a child, so if you have a problem with it, you can not tell him or her. However, medication abortion can sometimes cause uterine adhesions and can cause infertility. If there is a pregnancy, or if the endometrium is thin at the time of the ultrasound and the menstrual flow is significantly reduced, a hysteroscopy is necessary and you will have to tell the doctor during the examination.
