Hi Holly,
Don't worry about offending anyone, lol! I think everyone on the board is trying to lose weight before TTC or at least actually conceiving. The effects of excess weight on fertility seem to vary from person to person. There are lots of stories of heavy women having successful (and uncomplicated) pregnancies out there. One website I found is
http://www.plus-size-pregnancy.org/ . There are lots of personal stories of pregnancies and births there. I completely understand being nervous about the docs. I'm not trying yet, but all of my symptoms are pointing to me not ovulating, so I think I might need help when I start trying next year. I'm also coming off Depo (my last shot was 2/03), so that's an extra complication.
I think it's fine for people to not wait until they lose weight. If we held up everything for that we'd never do anything. If the doc says anything, just find another one. Feel free to ask his nurse on the phone what his policy is on heavy women.
Good Luck! Keep us posted!
