Symptoms gone

Sydney

I’m 7 weeks and five days and I feel absolutely nothing anymore... just last week I was nauseous, throwing up, tired... now nothing. My boobs don’t even hurt anymore but they’re still full. I got a sono last week and everything was fine, but I’m just losing that pregnant feeling. I have been eating like crazy but today I’m not even hungry. Should I be worried or is it possible for symptoms to just stop?
