Many of the ob-gyns cited this as the most common concern amongst their patients, especially for those who personally oppose abortion. However, according to Wendy Askew, MD, a board-certified ob-gyn who's been in practice for more than 20 years, the reality is that the morning-after pill works to prevent an egg from being fertilized in the first place, by disrupting the normal process of ovulation.
Dr. Alex Polyakov, an ob-gyn based in Melbourne, Australia, added that the pill will not harm an already established pregnancy, and therefore does not have anything to do with abortion or miscarriage. Instead, the morning-after pill simply delays the release of an egg, or otherwise prevents fertilization or implantation by thinning the uterine lining, for example.
