Welcome to icliniq.com.
The question is not entirely clear. Have you already aborted or yet to bleed, and what is the name of the pill? Any pill used for abortions are safe and have to be taken in full and advised doses to get the best results. They never affect the uterus adversely. They are usually hormones, so do not stay in your body beyond the particular cycle.
They do not affect your health or your future fertility potential or future pregnancies. You will continue to have periods, as usual. You can have a normal sexual life, and healthy pregnancies in the future. If bleeding has stopped, have a pelvic scan to confirm if the uterine cavity is empty or any tissue is left over. I hope I have clarified your query, do write back if any more questions, and for your feedback.
