I wasnt clear enough on my last question could this be implantation bleeding? please only women experienced it?

On my first day of ovulation my boyfriend and I had sex unprotected because the condom broke, before my period I usually get really bad cramps but the day i was supposed to start which was on the fourteenth it never came, i was three days late yesterday, but during the yesterday morning i had a light brown discharge like i usually do when my period is over, then later that night i had light pink blood when i wiped, so i thought my period started.. i checked again i wasnt bleeding anymore and it turned brown again.. could this be it?
