Hello I appreciate your query. First and foremost, medical abortion pills are meant to be taken under medical supervision only. You need to confirm exact dating of pregnancy as well as confirm that the pregnancy is intrauterine. Excessive bleeding and failure of medical treatment may occur, so you need to be under medical supervision in case you require an emergency surgical evacuation. So please do not take a risk and proceed on your own. Further, If you are RH negative blood group, and your husband is positive, it was already very careless of you not to take the RH antibody last time you underwent an abortion. It significantly increases your chances of isoimmunization. Please do not commit this folly again this time, because whenever in future you would plan a child, you are likely to face major complications. Hope you understand.
