3 days late...

ams

So I need some advice...I’m 3 days late, I had some brownish spotting on the first day AF was due, I’ve had mild cramping everyday nothing like period cramps. I want to test BUT I tested last time I was late for my period and i got a BFP and then my period started 4 days later. So I’m nervous. Should I just wait 5 days? I’m going nuts lol
