Can I have medical abortion 10 weeks into pregnancy? Leave a reply Expert’s take Medical abortion cannot be done after 10 weeks or 70 days into gestation. This is calculated from the date of your last menstrual period. Termination of pregnancy using the abortion pills is possible only between the 4th and 10th week. With increasing time in this window, the efficiency of the medication decreases. In fact, towards the 8th week, possibilities are that you may require two dosages of the abortion medication. However, the overall efficiency of these pills is about 94%. To have an exact idea of whether you are eligible for a medical abortion, it is important to have an accurate estimate of your gestation period. How many weeks pregnant are you? There is no way to determine the exact day a woman conceived on; not even formal clinical assessments. Trained medical experts mention that one can depend on the date of the last menstrual period (LMP) to know about the advancement of their pregnancy. Though not exact, the first day of your last period is considered as your day of conception. This is for convenience purposes. Moreover, the implantation also doesn’t follow a specific number of days exactly in every woman. Women who use ovulation kits also calculate pregnancy from the day of ovulation they suspected. This method will determine your pregnancy to be about two weeks lesser than what was indicated by the previous one. It is important to be informed that abortion pill kits are designed to follow the LMP method. Many females also face the problem of irregular menstrual cycles. In that case, an ultrasound may be necessary to determine the age of pregnancy by noting developments in the fetus. The consequences of an early abortion Pregnancy can be detected earlier than the dates that fall in the abortion-acceptable range. At early stages like these, however, it isn’t possible to differentiate between an intrauterine and ectopic pregnancy. This is because implantation of the embryo is required to determine if it is developing within or outside the uterus. The case of fetus development external to the uterus is called an ectopic pregnancy and is a serious medical condition. A very early administration of abortion medication may also not have any effect at all. Their mode of action requires implantation of the fetus. And, Implantation takes a few days after conception. The primary abortion pill, Mifepristone works by bringing about decidual necrosis to disrupt the link between the endometrial lining and the fetus. So, if pregnancy hasn’t developed to the extent required for action, abortion will not occur. What happens after 10 weeks? Medical abortion at 10 weeks or later is associated with a lot of risks. By this time, the embryo in the uterus progresses to the fetal stage. A strengthened connection is established between the placenta and the fetus. At this stage, a complete abortion may not be possible using just medication. Pregnancy may either develop further without hinderances or the uterus may be left with an unviable fetus that poses risks for an infection. Medical abortion is thus highly efficient only if done at the right time following the correct steps.
