IF I DON’T PUKE?

So if I’m correct, I’m about 6 weeks and 4 days according to a few pregnancy calculations.

Last period I had was on October 19th & has unprotected sex, I haven’t took a pregnancy test yet but I’ve experienced frequent urination & smelling is strong

The only thing is that I haven’t thrown up yet & I know around this time is when it usually happens ... but nothing so Can I be pregnant?
