Can you lose weight while pregnant?

Alex

So, I'm almost 12 weeks pregnant and dilatation desperate to do something about my weight. I've been nauseous since week 6, and the only things I've been able to stomach are starches and carbs. Bread, potatoes, pasta, crackers, etc. Needless to say I've put on more weight than I should have this early. Now that I'm starting to feel better, I'm cleaning up my diet and plan to start working out again.

My question is, will I even notice a difference or have a screwed myself over this pregnancy? I know I'll have the belly (duh), but can I still lose everything else?
