Hello dear Understand your concern If abortion will complete normally it is very difficult to say about the abortion. But incomplete abortion or if some retain product remain inside the uterus, it easily detect by USG scan. Never take abortion pill at home without guidance of gynecologist as it cause serious complication that require surgery. But you have to require follow up visit an USG scan after 14 days of abortion to know whether your abortion is complete or not for safe practice and to prevent complication in future. Hope this may help you Best regards Dr. Sagar
