Implantation or something else ?!

Nayeli

Hey ladies so I have been having light pink and somewhat brown spotting with cramps. I did have it with my boyfriend during ovulation almost kind of everyday. I also had it near the end of my period and before my ovulation started. (Unprotected) But tomorrow is my last day of ovulation. Could this be implantation or something else. ( and I already got my period this month)
