Advice re questions to ask.

Hi lovely ladies. It's been over two years since I came of bc & my periods have been all over the place since then. Hubby and I have been ttc since December 2012 without any luck. I haven't been to the doctor due to moving from England to the U.S.A and not having health insurance. But now hubby has a good job it means we can get health insurance, although it doesn't kick in for a few months. Anyway, thankfully I've managed to get an appointment with a nurse practitioner at a health centre & I was wondering if you could give me some advice on what questions to ask her? I'm clueless to the tests/drugs etc to ask for re ttc. Plus somewhat embarrassed that a 44 year old is seeking help. Just would love your opinions. I'm excited, yet scared about it all. Thanks :) x
