Would you test?

I got my period on the 17th. I bled pretty normal, 3 days somewhat heavy and then two days spotting and then on the 27th I wiped and had pink discharge (which I never had before and it didn’t happen again) but I’ve been cramping on and off again since and excess discharge today. I had unprotected sex 2-3 days before my period. I think I’m just over thinking it and that there’s no way I’m pregnant since I had my period.
