Desperate

DH and I got married June of last year, I stopped my BC in May and we started ttc June. We fell pregnant in oct and were estatic. That ended in a miscarrage at 6 weeks. I was diagnosed with PCOS when I was 19(now 24) I was put on bc pills for 4 years so when I got off my cycles were normal 30 days. It's been almost 6 months since my miscarrage and my cycles are 70+ days. No + ovulation tests, no change in my bbt. Basically I've come to the conclusion my PCOS is in full gear again and I'm not ovulating. I'm so desperate to fall pregnant again and I need advice on what I can do. Does anyone have any suggestions??!!
