Miscarriage Support - Scottish Care & Information on Miscarriage

Hi
I've just been diagnosed with polysistic ovaries. I do not know a lot about it. I have seen websites that say I can become infertile which is really upsetting as I would love to have another child. I had one child 11 years ago and Im not too sure if my condition has gotten worse to prevent me from having another. My period has been getting shorter & shorter for the last 3 months, could this mean I am becoming infertile. I would love to hear from anyone who has the same condition or who knows anything about it. It would be great to hear about anything I could do to reduce the loss of fertility or preventing diabeties.
