Food aversion in 5 week 5 day

Sj

From past 2 days I am not feeling like eating anything. Looking at food and food smell making me feel nausea. I have not vomited yet but just the weird feeling. I am having food for myself and baby even if I am not feeling like. But I wanted to know from community is it normal? Do anyone else feel like this?

Untill 5 week I was super hungry and gained 4lb weight as well.
