Implantation or ovulation?

I have PCOS and I feel like I’m having sharp pains intermittently in my right ovary which is tolerable but has been on and off all day today. I also had about a 1pence size spotting when I wiped this evening with light pale pink blood. I’ve been napping in the day for the past few days too. Do you think this is ovulation or implantation?
