I'm 10/11 weeks and and starting to feel rather fat! I've put on a few pounds but I really have gained a tummy! It doesn't appear to be a bump at all just fat? I've always been quite slim (with the aid of eating well and gym) I'm starting to get concerned now as of Christmas none of my troucers fit so am already in maturity troucers and now a couple of my tops are quite tight? Is this normal?
