TTC with PCOS

Hey y'all. Is there anyone else TTC with PCOS? I was diagnosed back in 2012 with PCOS. I have tried almost everything I can think of from vitamins to prescriptions. My cycle had been good the first year with being on metformin. 2013 my cycle stopped. I quit the metformin and my cycle began. 2014 I had a normal cycle up until October. Here we are 2015 and still no cycle. I feel drained all the time and hormones are all out of wack. I even went to donate blood at the beginning of January to help me feel less sluggish. Have any of y'all had success with getting pregnant while having PCOS? If so, what did you do to help? Thanks in advanced ladies!
