I'm so sorry. I empathise you -
I really, really do. I'm a carrier of Thalassaemia; sure, I technically can carry children, but, there's a very high chance that they'll be born with a lot of health problems and I would never put my child any child through that suffering. I treat myself as barren (what dude would want a handicapped child).
I read somewhere about your diagnosis, though.
PCOS is one of the most common infertility issues. Treatment can involve medications such as Metformin (used for diabetes) or Clomid (used to induce ovulation). Diet and exercise should also be part of PCOS treatment. It is still possible to get pregnant with PCOS, many women do. See a fertility specialist (reproductive endocrinologist) for more information.

here.)
I think
this article may be informative as well. I don't want to give you false hope - I'm no specialist so I don't really know the full scope of this matter, but I just can't bear to know someone else is going through a turmoil like my own - it's really cruel indeed. Don't give up on yourself though.
I give you all my faith and best wishes.
