5 weeks. Food is not appealing.

5 weeks and started feeling nauseated on and off all day. It popped out of nowhere at exactly 5 weeks (by my calculations) basically I don't want any food at all. Thinking about food makes me nauseous,

Eating food makes me nauseous, smelling food makes me nauseous and whenever I eat it just sits in my stomach...

I can imagine this getting worse at 6 weeks.
