Hiya - and welcome!
I would check out the PCOS sticky to get more info, were I in your shoes. There's also a ton of info out there for PCOS ladies - one good one is
www.pcosupport.org.
To answer your last question, yes, PCOS often has fertility complications - that's how it was diagnosed for me. I had wacko periods for several years, some times nothing for 6-8 months, sometimes bleeding for two or three months at a time, bleah! However, some ladies with PCOS have no troubles with feritility, and some can take glucophage and get pregnant no problem. My reproductive endocrinologist tells me that really the syndrome is not well understood, especially why it might present in such varies ways. Not all PCOS gals have weight gain, or acne, or skin tags, or even the "string of pearls" ultrasound that is supposed to characterize the syndrome (multiple ovarian folicles in cyst phase without egg release). You just have to have enough symptoms on a rather long list to be qualified for our august company.
My advice would be, start getting chummy with your Ob/gyn and have them refer you to an RE sooner rather than later. One who has experience with PCOS would be ideal, but aparrently the incidence of the syndrome is increasing, so more plain ol' practitioners are learning about it. Having a good relationship with those two doctors is a great first step.
Good luck, and keep checking in to let us know how you're doing!
