Full but hungry?

Keirsten
I'm 12 weeks 2 days. For the first 10 weeks I had no appetite so I hardly ate but now I've gotten my appetite back. I was wondering if anyone ever stays super hungry even though your full? I ate dinner and I feel like I wanna go back for seconds but I took a bite and felt like I was going to throw up while chewing because of being full. I've waited a few minutes and I wanna go back for another bite lol.
