HELP! Retest? Or wait

I’m 5 days away from period been cramping bad. Last pregnancy I thought I was going to start my period and didn’t because I was having cramps as if I was going to start.

I took a digital and it says not pregnant but I kid you not I’ve been nauseous and so fatigue and almost got dizzy standing up. I did have unprotected sex while I was on my cycle last month and couple days before I ovulated just curious should I just wait to see or use a different test also noticing a drop in my milk that I pump.
