Are there any ladies that have suffered polycystic ovaries that can offer any advice?

My girlfriend and I have noticed her mood swings and the irregularity of it all since she came off the pill. I find her moods utterly unbearable (check into a hotel) and she claims she knows it's happening but can't stop it, then gets very tearful afterwards. We are considering starting a family. I told her to get checked out. Anyways she had an ultrasound today and the imaging Dr said she could see follicles on her right ovary but was struggling to find her left one.
She has requested a blood test to confirm her findings.

How manageable is this? And if you've had children, how easy/tricky was it to conceive?
