Ovulation in clomid

Hey ladies! For those who have taken clomid, did it ever cause you to ovulate a week late?? Its been very hard to pin down when I'm ovulating. I dont use the tests bc I can normally tell by my body (pain). But last Wednesday when I should have ovulated I thought I did. Then that Friday I had more ovary pain and now I have a constant pain in my left ovary...just trying to figure it out so we dont miss our window! We've been bding everyother day since the 24.
