Not Pregnant but feeling 🤢🤮

For about 2-3 weeks on & off I've been feeling extremely nauseous. I'm talking like if you have a horrible hang over and you don't want to see food & you just want to throw up so bad. And I do end up throwing up.

But today I took a test & it's negative. I'm do for my period Thursday so I don't know if it's too soon or if I'm just not pregnant & something else is wrong.

I work in a clinic so we get checked everyday for any covid symptoms. I don't feel sick at all. I just feel nauseous on and off.
