Implantation bleeding?

Angelica

Hi there. So this morning I woke up to some light spotting, it took me by surprise because I recently got off my period on Christmas’s day. I was in my fertile window (I believe) on January 1-6th. I never spot in between, I had light cramping. I had intercourse 6 days ago and everyday in my fertile window except one day. I’ve been trying to conceive since July of 2018. So I’m confused as to what this spotting would be. I did have intercourses last night and maybe my boyfriend was “too tough” please help. It did not last long at all. I dont even know if that’s possible to be implanting that soon. My period is due on the 29th on January and is pretty consistent and last about 4 days.
