Makensey

So I am new to clomid first month. I am currently cycle day 9 took clomid days 3 to 7. Don’t have regular cycles had to use provera to start cycle. I have PCOS and new to using OPKs. I tested today at about 6:30 in the evening. Only held urine for about two hours. Having slightly crampy ovaries. What time is the best time to test using OPKs? Anyone else use clomid on 3 to 7 when did you O? Below is pic of first test on cycle day 9. I know it’s negative
