Implantation bleeding or AF?

I had some spotting last night and this morning. It’s not a consistent flow, but more just when I wipe or a drop in the toilet... Most was a light pinkish but one was a little darker(like AF more). Didn’t have implantation bleeding with my first so no idea if that is what this could be??? 3 days till AF is supposed to come, and 11 days post ovulation. Going to test tomorrow if not heavier bleeding but just trying to stay positive until then but also not get my hopes up...
