So depressed..

Chrisann
My AF was due on the 16 still haven't got it. But all test say negative.. I was on 100MG of Clomid and 1500MG of metfromin. I have PCOS. When should I call my doctor for him to prescribe me another round? After a miscarriage November 24, 2014 I am slowly getting more depressed as time proceeds.. I just feel like there is no hope for me :(
