I feel like I have gained too much weight. I'm now 30 weeks pregnant and know I have to gain enough weight to have a healthy baby, but I'm really scared to put on any more lbs! I want to start dieting I mean I eat pretty healthy, and not like large portions so I'm just wondering where the hell all this weight is coming from! Like it cannot all be baby.
