Implantation or period???

Okay ladies. So my SO and I were intimate and on New Years (go figure lol) and he came inside me. We did it again on Friday and again he came inside me. I supposedly ovulated the week before that. I’m also supposed to start my period in 4 days (so on Thursday). Well today after being intimate I went to pee afterwards and there was very light pink blood when I wiped. Like so light pink you almost couldn’t see It and I was cramping like I was about to start afterwards and not again since that. Is this likely implantation bleeding or am I being crazy??
