Implantation bleeding? Pls help

I’m on the implant (nexplonan) and me and my boyfriend had sex last night not even longer than 3mins cause we switched to something else but he didn’t nut at all or was even close. But here’s the next day is this my period or implantation bleeding? Btw I’ve been on it since 1/22/20 and this is my first time bleeding

This is the first day^^

This is the 2nd day ^^^
