Yeah, I figured that as well, dragoncookie. My feelings at the moment in that regard are that they can do as many tests as they want on me, so long as it helps me get my homebirth. (Aside from an amniocentesis - I can't see any reason they might want to do it anyway but still...)

If they say I can't get a homebirth because of my size, by god I'll try to lose some - healthily of course - and try again. I never thought this would be so important to me, but now I'm actually planning it, it really is...
