When did everyone start feeling nauseous ?

As soon as I turned 11 weeks I get so nauseous. Before it was when I was hungry around 5 weeks and then stopped. But now I get nauseous out of nowhere for no reason. And on top of this I can only eat what I desire. I cook Hispanic food everyday and I can't eat that. I can't even stand the smell of rice beans coffee and meat or chicken. My list is starting to grow day by day. 😷😷😷
