Clomid tips!

I've been ttc since June 2015 I fell pregnant in October which ended in m/c at 6 weeks. I've been trying actively to get pregnant since. My cycles are now 90+ days, I take my bbt and opks and never get a +. I was diagnosed with PCOS. But was on bc pills for 4 years then fell pregnant when my cycles were regular. I saw an OB in March who took u/s on cd 60 and said she saw very small follicles on my ovaries that may drop, after that I didn't get a period for another 30 days with no + opk. but was not willing to prescribe me Clomid until October. I now get to see a new OB since my last one was very rushed when seeing me. I get to see her on August 3rd and I want to ask for Clomid but don't know how.. I'm so afraid I'll get turned down again! any advice on how to ask??
