Is it too early to ovulate on CD9 or CD10 on first round of Clomid 50 mg?

I took Clomid 50 mg CD 5-9 and on day 9 I had a lot of clear, EWCM with a twinge of blood and the next day when I wiped, it was creamy and tinted pink. I also remember I had serious cramps the night of CD9. Could that have been "O" already? I didn't start digital OPK until CD13 and so far negative (on CD18 today).
