Hey Tissy,
None of your problems are insurmountable.
You'll find loads of ladies who have PCOS who are TTC and having success. And a retroverted uterus doesn't have any impact on your fertility.
Your DH may be frustrated but not with you - more with the situation and the fact that he has no control and no way to fix this (you know men, they love to fix things).
I'm sure that you will find support and encouragment here. Learn as much as you can - i found it really helped. It gave me something to do and made me feel like i had some choices and a little bit of control.
Good luck.
