Progesterone issues

Jamie • TTC since July 2014. Two angels in heaven, Oct 2014 & June 2015
So I'm having issues ovulating. I've done one month of clomid and took two blood tests with no luck. The dr is upping my clomid to 100mg next month. My cycle ranges between 35-45 days and it hasn't been consistnant for months. For anyone who's dealt with these issues longer I need some insight. Any advice suggestions welcomed!
