Implantation bleeding

girl

Ladies I need help.. Could this be implantation spotting? I don’t know when I ovulated and I didn’t have vaginal sex. My period is due in 4 days and I took an early sensitive test that turned out negative. I just made out with my boyfriend (I was on my period) but the last day of my period he touched my vagina but I’m not sure if he has anything on his hands.
