I'm 7 weeks pregnant and feel like I'm starving all the time. I didn't think I'd be this hungry all the time, especially since I read you don't need additional calories in the first trimester. But I am so hungry all the time. On the way home from work I pulled into a Which Wich to get a caprese sub as I knew a normal snack wouldn't hold me over 'til dinner. At this rate I feel like I'm going to weigh 500 pounds before I know it!
