What do you guys think?

Im supposed to get my period tmrw, but I haven’t had any cramping or nausea. Usually I get cramps 2 days before my period starts and I haven’t. Today I went to pee and when I wiped, there was light pink spotting and it looked like implantation bleeding which I know how that looks because of my first pregnancy. Could I possibly be pregnant? I had my ovulation 12 days ago, and I had unprotected sex 3 days after ovulation was over.
