did anyone's obgyn tell you that you had to have at least 3 periods of your own in a row for her to give you clomid?

I'm confused as to why my obgyn said in order for me to get clomid she said I need to have 3 periods of my own before she will. My periods are wacky and don't come like they should and I know for a fact that I don't ovulate. Couldn't I take clomid with periods from provera??
