I had a consultant apt a couple of weeks ago as have a high BMI (35), I'm 5'4 and a size 18, about 95kg so definitely overweight. =\ she said that weight can have an impact on labour and some women end up with a c-sec but that she wasn't concerned. I think its more precautionary that they tell you as she seems I fased by me saying I'd rather do it naturally. She said she had no worries for me so I'm sure you'll be fine hun xx
