Threw up tea? Pregnancy symptom ?

So this morning I asked my s/o to get me a sweet tea bc I wasn’t really hungry yet and I ended up finishing the tea about 2 hrs after I got it and then I threw it up. It’s not like I drank it so fast it made me sick bc I usually go through a large tea faster than that. I never usually eat breakfast and get a tea on an empty stomach & it’s never made me throw up??? So I was wondering what it could of been and if it was possibly a pregnancy symptom? Might be a stupid question but oh well.
