Implantation? Wrong ovulation?

MamaJ
I thought I ovulated on April 7th. At what I believed was 8 and 9 dpo I had cramps and ovary twinges..now I'm wondering if that was ovulation pain. 
​Today I had pink spotting. Only when I wiped, it wasn't super heavy. I wore a pad but none ever made it on the pad. It lasted for an hour and a half. Then disappeared. This is strange for me because I never have spotting.
​Assuming the pain I felt was ovulation that would put me at 6dpo. Could this be implantation bleeding or is it too early?
