5w2d my appetite sucks

Jamare • First pregnancy so i hv a mountain of ques
I haven't had any true nausea. I'm 5 weeks and 2 days. Doc said I'll be experiencing it really soon. I do know tht my appetite sucks. Seems like I'll be hungry and eat but after a few bites, I'm disgusted with it. And a hr later I'm hungry again... HELP! Is this happening to anyone else?
