TMI Is this the start of my period or what?

I just wiped and this is what appears. I haven’t had my period since a week before Christmas. I’m actually in the process of talking to my doctor about what to do with my periods. I was also told I have pcos two weeks ago and we are waiting for my referral to come in before we make the next step. Me and my husband just got done having sex about an hour ago....is this the start of my period or implantation bleeding? Reason while I’m asking is because I never have it this heavy when starting out and it’s more pink then red.....

EDIT: I know this isn’t implantation bleeding from my sex today. I’m talking about from any other time I had sex in these past 4 months.😂
