I’m stressed over this!

Kase

So me and my partner had unprotected sex,

He came in me which was an accident (oops)

The month after that (which was a couple of days after since it was 2 days at the end of last month)

I had my period 2 or 3 days late but I’ve been putting myself under a lot of stress lately so I’ve been getting mild cramps for 2 days? Am I paranoid or actually 4 weeks pregnant?
