i can honestly say i hear you and i feel you on this one. i am going for my surgeon consult on the 6th and should be setting a surgery date that day. i am not preventing pregnancy in any way until after the surgery. i doubt it will happen but hey, it isn't unheard of.
now...do i want to be healthier before i try to carry a child? absolutely, that's was one of the major deciding factors for me in going through with this finally. but if it happened for us before the surgery after not preventing it for 2 years now, would i regret it? probably not. i think i would consider it a miracle and a sign. but i know i would still have the surgery afterwards. after all, it's still about MY overall health.
good luck in your journey!
