When did I ovulate?

I took clomid for the first time this cycle. And I am afraid I missed my o date if I in fact o'd. I have been opking since cycle day 9 well middle of the night last night I had pains on my right side. Can you tell me if I surged. I thought it was new here are my last few days of tests cycle day 12 is today's. Should I keep opking.? Tia
