I'm 4 days late for my period, I'm on bc and have always also used condoms. I took a first response test this am and it was negative. I have been pretty stressed the past week or so as I've been going through my first ever breakup from a 10 month relationship so maybe it's just late cause I'm stressed? Should I just wait for it to come or test again in a few days? Any advice/info would be appreciated.
