Hungry😭😰 ALL THE TIME

I just ate a banana, pb&j sandwich, a snack bag of doritos, and now starting on a cheese stick and goldfish, i wanted pizza so badly but im stuck at work until four! I feel like all i do is eat but i havent gained a pound since 12 weeks and my doctor asked me at my 16 week appointment if i was eating 😐😐😐😐 really lady? Thats what my whole day revolves around! Food!
