Clomid question

Sandra
I am on day 3 of clomid, I've been taking them at night so I wouldn't really have side effects. Well real early this morning around 3:30 am I had this pinching on my right side which I've never experienced before. I have mild pcos and I'm not suppose to ovulate until around June 7th. Has anyone else experienced this kind of symptom? I'm not real sure what it is.
