Clomid question!?

Kristin • Been married 8 yrs, actively TTC for 6 yrs. I have PCOS & insulin resistance and never ovulate. My cycles are 100+ days. We just finished our fourth round of clomid.
I'm on cycle day 6 (Induced by provera). Still full bleeding and heavy cramping. My normal periods last 3-8 months bleeding non stop. So I've been worried that this period will be the same. This is also my first round of clomid days 3-7, so tomorrow is my last pill. Has anyone else with irregular periods used clomid? Will it end eventually if I'm "supposed" to ovulate day 14ish. Or how long should I bleed before telling dr. Thanks everone!
