How come I am only almost 13 weeks pregnant.. but I look about 5-6 months.. everyone keeps telling me I look so big and that you can deffinetly tell I'm pregnant... and plus I'm having twins... when having twins does that make you grow bigger faster.. my last pregnancy ended in a miscarriage at 18 weeks and I never grew and didn't gain any weight.. but now I look so big.. and I have also gained 13lbs... is this OK.. has anyone had this happen to them
