Welcome Rach! I found this forum coz I was researching my PCOS, and I've found everyone here really helpful. I had no period for 10 months and was diagnosed with PCOS in April... and as you can see on my ticker... am already pg! So don't be too disheartened with what you can read on PCOS.

A basic explanation is that the eggs in the ovaries aren't maturing properly, and aren't being released (ovulation) and this causes the cysts on the ovaries (you would have seen the cysts on you ultrasound).

I'm not sure if they know the exact reasons this happens, but it's basically an imbalance of hormones.. such as too much androgen.. which prevents the ovaries from releasing some other hormone.. which makes the cycle work nicely. lol... I really can't remember which hormones do what.

The reason I'm on Metformin, is they believe that insulin resistance contributes to this malfunction of hormone production, and the Metformin alone has worked with me... so my PCOS must have been related to this insulin resistance. Of course, others have much more trouble with their PCOS, so I think it can be different for everyone.

I'm sure my little explanation was as clear as mud! Someone else is bound to jump in and explain it a little clearer

Good luck with any treatment you start on!
