Late 3 days….

Sooo. I always feel dumb asking these questions. But. I had unprotected seggs on Feb 6. I was on my period so I couldn’t tell if the guy came in me and we were both drunk. I asked if he did but he doesn’t think so and also can’t remember. Well fast forward to today when I should’ve already started my period, I’m 3 days late. I am on the pill tho. But I did spot feb 19-21 and my last period cycle was February 4-8.

I’m having slight period symptoms like cramping and lower back pain but I do usually have tender breasts which I don’t yet. Idk. Should I take a pregnancy test? Any chance I could be pregnant? I’m really hoping tf not though bc, I don’t even talk to the guy anymore and I just don’t want a kid. I got enough crap going on in my life right now 😔

Is it possible to skip a period entirely while on BC?
