Don’t feel pregnant

Hi, I’m first time mom, week 7 and I have been feeling very bad since week 5 and suddenly now at week 7 I’m totally fine after having some constipation and nausea medication my obgyn has prescribed. I have been feeling alright for 2-3 days now. I have been so so sick till I can’t even eat but I’m feeling completely normal now and my appetite is back, it should be a good thing but I dk why I’m so worried. I have no bleeding but very mild cramps. Anyone face the same problem? It’s causing me to be very anxious.
