I have never understood why, according to the WT, JWs are okay (conscience matter) with birth control methods like the pill, mini-pill, Depo-Provera, and IUDs. I am not trying to spark an abortion debate. But I was actually angry at the WT when I started researching how the mini-pill prevented pregnancy. Research it for yourself! My spouse and I felt betrayed by the WT because they did not provide the proper spiritual food for us at the right time. I still remember praying and asking Jehovah for forgiveness for any life that was unknowingly aborted.
So, the WT condemns those who accept a blood transfusion but make it a conscience matter to have an IUD which does the following:
The IUD is generally accepted to work by causing the uterine lining (endometrium) to become incapable of accepting the implantation of an already fertilized ovum (i.e., a human embryo).
