I had a 36 week scan/check up today and have gained 19kgs in total (so far!). The widwife said average was 15kgs. Was just under 9stone 9 (am 5 8) when I got pregnant, and to be honest most of the weight appears to be on my bump.
I used to work out 5/6 times a week so was probably bound to put some extra on because I had to give up exercise two months ago. But still!!
