Can we talk about my fat ass?

Ugh, I am disgusted with myself right now. I am only 13 weeks pregnant, but look closer to 6 months because of all of the weight I've gained. I had my 2nd OB appointment yesterday and nearly cried when I stepped on the scale. I've gained 10 pounds since my last appointment 4 weeks ago. TEN FREAKING POUNDS IN 4 WEEKS!!! I don't know what to do. I don't think I have been eating horribly. While I'm no poster child for healthy eating, I haven't taken this opportunity to eat whatever I want. I'll admit I've had some cravings for junk like tastykakes and cheese danish, but I've been trying to eat that stuff in moderation. The only thing I've added to my diet is a couple of cups of chocolate milk (but it's 1%...can it be that much worse than the 2% milk I was used to???).

I think the culprit is mainly due to my PCOS. Prior to trying to conceive, I had lost 30 lbs on weight watchers. When I went off the pill in August of 2008, I was still counting my points and watching what I ate, but the pounds slowly started packing on. The next thing I knew, I had gained 38 pounds by my first RE appointment in August 2009. Even once I started Metformin, the pounds kept coming. I've added 18 pounds since August.

I just don't know what to do. I'm worried about gestational diabetes. I'm scared of getting yelled at by my doctor. If I was eating ice cream and ho ho's all day, I'd at least know I could do something about it, but I'm not. Obviously I am not trying to go on a diet, but if there was something I could do to slow down this weight gain, I'm open to suggestions. I think I will start walking on the treadmill. I really have been pretty inactive for the past few months, so maybe walking will help.
