While Justin was at the Memphis School of Preaching we were told this. There was debate, though, if it was true. We looked into it for ourselves and couldn't find any information on it. I looked at the pill I was on's website and couldn't find anything. We talked to a member of the church who is a pharmacist and we were assured that's not a method the pill used. (I guess it's just not widely known.) Some time after we moved to Demopolis I was having a lot of trouble with frequent migraines, depression, fatigue, mood swings, etc. I was trying to figure out the problem and looked in to the side effects of the pill I was on. It seemed that it was the cause of those things. I also found a section on how my pill worked and there it was. A section on the back up method that could cause a perfectly good fertilized egg to not be able to attach to the wall of the uterus. As someone who believes that life starts at fertilization (Psalm 139:13-14), I was devastated. Had I unknowingly caused a chemical abortion? How many had I caused? Needless to say, I stopped taking the pill.
After Reagan was born I asked my doctor about it as well. I told her I had read that a fertilized egg could be flushed out because it couldn't implant and that I believe life starts at fertilization. She said if I was uncomfortable with that then condoms were the best choice.
I wish I had known this sooner. I wish I had shared this sooner. I don't know why I haven't shared this before.
I encourage you to check this out for yourself. Here is a link to the page for Ortho Tri-Cylen Lo. Click on Secondary Methods and it plainly tells you it impedes implantation.
I just want you to be informed.
