Advice Please 😅😅

Okay so I get bad anxiety so it’s hard to trust my “gut feeling” I need some advice. I had unprotected sex with my bf, without a condom, he pulled out super early and did not cum inside of me.

When it came time for my period it was a day late, super light and only lasted like 2 days...

Now here I am about a week after said “period” and am super nauseous..

Am I just freaking out, or could I be pregnant?! Please give me some advice 😅
