So to start off i had sex on the last day of my period, I’m on the pill but I’m still freaking out because I’m 6 days late & I normally run like clockwork. I have been spotting a dark brown/red with clots( like end of period ) but nothing like my normal period. I took 3 tests and they all came back negative. I will say it may be late because of the stress I’ve been under for finals and but I just need some advice/ opinions on what y’all think is going on ?
