How were your periods when you were taking clomid? My periods for the most part start around the same time each month (give our take a couple days) but my periods last anywhere from 1 1/2-3 weeks. Lately 2 weeks. My doctor prescribed me clomid cause I wasn't doing well on metformin (it was making me dizzy and fatigue). Was anyone prescribed clomid with periods like mine? If so did it work?
