Implantation?

Saturday was my last day of my period, so my partner and i had sex and he came in me. Today we had sex again and about two hours later i was bleeding but im not sure if it’s implantation. The other days we had sex we didn’t use a condom but he did make sure to pull out. Im so lost because i feel like its too early for implantation since i did just get off my period. Any thought?
