Oh Fiona! I am so sorry honey! Don't know what to say, but just want to send you heaps of I too have PCOS and have been TTC for months. I won't say I know how you feel because I don't, but I DO know that it hurts.

Don't be so hard on yourself.
I'm their best hope
It really wasn't up to you - these things have a mind of their own. Just hang in there, hun. Hope your DH is with you soon. I will be thinking of you.
