I had dessert with a physician friend of mine on Friday night. The topic of birth control came up and she informed me of something that she learned within the last 2 years which has changed her understanding of the pill.
The American Gynecological Society defines a pregnancy as the implantation of a fertilized egg. Therefore, it does not consider a fertilized egg a pregnancy. So, when your doctor tells you that the pill is safe and it does not cause "abortions" of pregnancy that information is solely based upon this definition of pregnancy.
My friend informed me that the pill is supposed to do 3 things:
- Prevent you from ovulating
- Close your cervix so that sperm cannot get through
- Thin the lining of your uterus so a fertilized egg cannot implant
My friend informed me that on the pill you still end up ovulating 3-4 times a year. Therefore, in theory it is possible for eggs to become fertilized but not be able to implant because of the other side effects of the pill. She said that there are no studies on how often this could happen nor will there ever be because no one is concerned because they don't consider a fertilized egg a pregnancy.
She personally gives all this information to her patients when they ask to be put on the pill. She said she didn't know this until about 1 1/2 ago and before that she had had no reason to question the pill and its safety and effectiveness.
This is new information for me and I believe it will be hard for you to hear this from you doctor, so I'm passing it along. Feel free to pass it along to any friends that you think might be concerned about this issue.
