So i went to a Christmas party withl my husband, all his coworkers were there. I met one guy and he was saying that im big and i wont ever lose weight after i have my baby. Are you Fucking stupid! You dont say that kind of shit to a pregnant woman, im already insecure because this is the biggest iv ever been even befor baby. But its ok i know ill lose it, and i acctually plan on really getting back into shape
