Clomid and OPK

Hi Ladies! 
I took my first round of Clomid this month (CD 5-9) and on CD 10, I had a positive OPK. I read that Clomid can cause false positives so I treated it as that. Today, CD16, I had another strong positive OPK. I typically ovulate a little early, around CD12. Would you treat today as a true positive, meaning I will probably ovulate tomorrow?
Thank you!:)
