Birth control? and odds?!
Question: Birth control? and odds?
Answers:
Nuva Ring is 99.9% effective. This means that 1 in 1000 women will get pregnant in a year on it. There is still that 1 woman though, and if for some reason something happens so you do not have that birth control, the pull out method (when done correctly, pulls out before ejaculation) is 96% effective. While it is not necessary to do this, it might be nice if you happen to be that one woman in a thousand.
I will note that pre-ejactulate can contain sperm so even if he doesn't ejaculate he may still have leaked out sperm so this is a disclaimer for for those NOT on birth control. For those on birth control, this adds a little extra security.
If he's a turd don't take your chances. Your kid would like anime.
