Hi Jo,
Firstly - don't be scared. It's easier said than done, I know, but you've got through the biggest hurdle any PCOS sufferer has and that's getting the official diagnosis.
PCOS can be scary, especially when first diagnosied but it's not the end of your life or your dreams for a family. Many PCOS sufferers, like myself, go on to have children, sometimes without any help.
With regards to conceiving my doctor told me that after 12 months of trying unsuccessfully I would be put forward for IVF - so this could well be an option for you. I was officially diagnosed after I had my daughter and after 2.5 years of trying without help (I, like you, also miscarried my first pregnancy after 2 yrs of trying). Had I been diagnosed previous to getting pregnant I would have definitely have taken the IVF route after 12 months. So ask your doctor about their procedures regarding this.
The most important thing to remember is don't stress. It won't help you mentally and doesn't help when trying to conceive either.
Being honest the majority of people I know, myself included, fell pregnant after a drunken night out
It's not the end of your dreams, it's just the start of you taking control of them!!! xxx
