Implantation help

Hi! I was wondering if I could be implanting. I had bright pink blood today. Super light, like two drops, and not like my period. I ovulate on the last two days of my period though if that matters. I was traveling for work and visiting family, and moving states into our new home. My bf and I had sex on Jan 3-5th. Is this more than likely my period? Or could it be implantation? I am supposed to start my period on Jan 9th so maybe it’s early?
