I can see that you have plenty of answer but no-one mention ( or maybe I was the only one) that after my 1st I really remember quite clearly that when I had to walk down to where they were keeping DS ( came to fast so he had to have some oxegen for 24hrs ) that my sagy defated tummy swayed with every step I took it was horrible. I didnt last long only a few days but that is the strogest memory I have of the 1st few days.
I am only a small girl so I went back to what people thought was my shape within a few mths ( as I can wear alot of dress's and lucky for you they are the big fashion right now), but really to get me back to my real size takes me about a year as I put on over 25kgs I cant see the scales after that and they dont weigh you up here, so I would have put on more as that weight in around 30weeks LOL but who cares you get a wonderful baby at the end. Good luck and enjoy whats to come.
