It drives me crazy that so many women do not understand how the pill works...how can you take a medication without understanding how it works? If you take it correctly, you do not ovulate. That is how it works. If you don’t take it correctly, your chances of ovulation are higher and therefore, can result in pregnancy. That simple. Literally got into a short argument with my doctor’s nurse because she did not understand that that is how it works. A NURSE?!? How? How is that possible? To become a certified nurse and not know how the pill works? Of course, just like any medicine, it does not work for EVERYONE, but still... Sheesh..
