Hello ladies

I have pcos and i was in bc and still on metformin to regulate my periods which it did help then i started my first round of letrozole last month but it failed i got my period the day it was expected and according to my obgyn i did ovulate my numbers looked good but i just didn't get pregnant she told me not to worry that it happens and for us to give it another try so she prescribed me provera to induced my period i took my last probera pill yesterday and just waiting on AF .....so i get to see my obgyn tomorrow so she could do an ultrasound and make sure everything is okay! Does this sound okay to u guys is there any success stories of getting pregnant in the 2nd round??
