Help !!

Me and my boyfriend had sex on August 8th and 9th .  I was fertile on the days between the 2nd through the 9th of August. We used protection every time we had sex and he did not even ejaculate inside me or anything . He only ejaculated once and that was during oral sex . He was more rough then he usually was. Two days after I began spotting brown discharge. My last period was July 27 and was suppose to get my period on August 23 . I'm 5 days late can anyone tell me why ? I took pregnancy test and they all say negative . Could that have been ovulation spotting ? I have been stressed lately because of college

If he was a bit rough, the brown discharge could just have a bit of dried blood in it. That's fairly normal, and unless it smells or persists for very long it should be fine. Just keep an eye on it! A bit of bleeding after sex isn't dangerous in itself, but could make you vulnerable to infection (yeast etc), so I'd suggest using a bit more lube during rough sex.
As for the delayed period, I'd guess that stress is the likely culprit, and focusing on eating and sleeping well is probably the best cure :)
