PCOS Struggles

I was diagnosed with PCOS almost 2 years ago which explained a lot of things especially my irregular periods. 4 weeks after I was diagnosed I found out I was pregnant and two weeks later had a miscarriage. After my miscarriage I started to have a period every month (this had never happened before and they were spot on same time for months)  I still continue to have a period every month, but now my cycle days are out of whack. From May-June I had a 27 day cycle and now from June-July it's almost 37days. (No I'm not pregnant and I'm supposed to start tomorrow) So my question: Does anyone with PCOS have this problem? Also, did your PCOS effect you ever getting pregnant?
