I started off at about 80kg with both my pregnacies. With the first one, the ob I saw was absolutely awful. She said I was obese, my baby would be deformed and that I could not go to the Family Birth Centre as I was high risk! After lots of tears and explantions that I had been much heavier (about 100kg) with no health problems she changed her decision and let me see the midiwives. Not a single midwife had any issue with my weight and I had no problems other than carpal tunnel. I did end up with an emergency c-section, but that was not weight related. I did gain a fair bit of weight, as I found the only way to deal with my m/s was to eat.

2nd time around I got carpal tunnel again along with spd. The only issue with my weight was this it made ultrasounds more difficult and there was a chance I would have to return for more in case they could not see everything first time around.
