If you want to take abortion pills for medical abortion, the best time is within 49 days of pregnancy, that is, less than 49 days from the last menstruation. Usually there may be some reactions 2-3 days after taking abortion pills, mainly nausea, vomiting, abdominal pain, diarrhea, and possibly dizziness. After the abortion pill, when the above reactions occur, there will be vaginal bleeding, when the uterus will gradually contract and expel the fetal sac tissue. However, usually the abortion may be incomplete and may require an ablation procedure. Do not have a medical abortion if the pregnancy is too long. If the pregnancy is longer than 49 days or even longer, abortion is generally recommended, which will not cause relatively much damage to the woman’s uterus and there will not be much residual tissue that will remain in the uterus to avoid prolonged bleeding, infection or other inflammatory conditions. Therefore, if you want to have a medical abortion, the best time is within 49 days of pregnancy, if more than 49 days or even longer, it is recommended to choose abortion.
