Implantation bleeding?

So today is 2nd day of "period". Period was right on time... had sex while ovulating on days app recommended highest percent to get pregnant.. Yesterday only had a few drops of really light blood when wiping... today I had this tampon in for 4 hours.... TMI I know... is this implantation blood or just a funky period? Took hpt yesterday and was negative... Opinions since y'all know when you want to be pregnant you can literally talk yourself into believing everything to seem pregnant...
