New Testing & Clomid

Cara
Ok so here we go.... 2+years TTC
Finaly the doctor brings up Clomid. We've tried other forms to help with PCOS, nothing helps. I asked her about doing a test first to make sure if I ovulate can the eggs even get to my uterus. So we are scheduling that first then Clomid next month if it's clear!!! 
If by luck we'll have a bouncy screaming pooping bundle of joy next year!!! 
So who here has used Clomid and who has had successful births? And also about how many rounds did it take
