Nauseous and no appetite.

I’ll be 7 weeks tomorrow, I haven’t really been able to eat for the last 3-4 days. I feel like I’m starving but nothing sounds appetizing and the thought of any food makes me want to gag. I have absolutely no desire to eat, and I have no doubt that’s making my nausea much worse. I try snacking or eating small things and it also makes me want to get sick. Anyone have any advice? I’m really struggling lately.
