Im 39 weeks and Ive put on 14kgs. Last pregnancy I put on about 12kgs and it all come off in the 2 weeks after I had my daughter cos most of it was fluid. This time its fluid as well but I weigh more this time to start with. I also weigh a lot more than u do too so maybe it depends on how much u weigh in the first place. A friend of mine put on just under 40kgs with her pregnancy and 20kgs came off in the first 2 weeks from fluid and then the rest came off over the next couple of months. Spose its different for everyone.
