Can an early period be caused by sex?!

My period is sometimes irregular, but for the past couple months it's been the same: It starts on the 1st day of the month and ends four days later!. I had pretty rough sex two days ago, and recently I've been, well, ahem, masturbating moderately heavily!. Today I noticed a little bit of a brown discharge, and I bleed just a tiny little bit when I pee!. Today is the 27th, so I should be expecting my period in about three or four days!. when I wipe, there's a bit of normal-looking period on the toilet paper, but that's only if I wipe really thoroughly and my fingers go a little up myself!. The blood is bright red and looks the same as all my other periods!. Did the sex knock out some of my period early, or what!?!?Www@Answer-Health@Com
