Implantation bleeding or not 7dpo?

Mandy
I had a positive ovulation test with lh surge 7 days ago and according to my charting I ovulated 7 days ago. Today I had light pink spotting when I wiped. Could this be implantation bleeding???? I also completed a 10 day prescription of Provera, progesterone to help regulate my cycle. Other than that I have really sore and tender breasts. I am really hoping for a bfp, but I know I can't take it for a few days. My Aunt Flo is 8 days out.
