We don't have a scale at home so I only know how much I weight at my monthly prenatal appointments. At 18 weeks I was already up 10 lbs, so I feel like I will be in the same boat as you! I try to be active but I am still sick so it's hard to get moving. I also still have a lot of food aversions, and carbs make me the least nauseous so that's what I've been living on mostly, even though we ate very little carbs before I got pregnant. It's hard when you know you are making bad choices, but your body just won't let you make the good ones!
