Good thread! I have thought about NFP for TTA, but never looked into any real information on it, thanks for the info. I have been on and off BC forever seems like. Presently I'm not on any and hoping nothing goes wrong in between now and August, I plan on starting another year at least in August. I'm not sure I want kids and most doctors won't let me make a permanent decision yet anyway. I'm just gonna try to play it safe for another 3-5 years or TTC, whichever comes first.
