Does clomid change ovulation day?


Hi! I am doing

<a href="">IUI</a>

this month and my Dr put me on clomid. I have been ovulating but my cycle lengths were varied so that’s why he put me on it. My instructions say to call if I don’t get a positive ovulation test within 5 days of my last pill, and today is day 5.

My question is, would clomid change my ovulation day if I was not having issues ovulating before taking it? According to my calendar prediction, I wouldn’t be ovulating until around the 21st without the clomid.

I am going to call, but wanted to see if anyone knew.
