Implantation Bleeding or Early Period🤔

Chimera

Me and the hubby had sex 11/16/2019 which was my ovulation day..Thumbs up right? I’m not suppose to expect my next period until 11/30/2019... I am 10 DPO and I’m experiencing light bleeding.. It started on the 24th which was 8 DPO... I’m curious of what can be taking place here... Is it implantation or my period... A blood test would be accurate right now?
