New mild nausea...any advice?

I've noticed that the past week I've been having weird episodes of mild nausea. Things I normally like are sort of making me feel off and sometimes literally make me feel repulsed. Is this something you have experienced? I've been lucky until now so this, at 6 weeks, feels weird since it's new. Any thoughts? Thanks. :)

It was texture for me. I still have no interest in a steak. Also when I'm full I don't like to smell food cooking. Yuck.
