Firstly, welcome to BB!

Wow, what an amazing story to tell, I really hope you have a very happy ending soon. I certainly haven't been through what you have been through (& your DH of course), but have been on a longish road to ttc our 2nd and about to embark on IVF. There is a thread for people using assisted conception (AC) that you might like to join in a coupld of months, but in the meantime I suggest feeling your way around the site and
'meeting' people in the many various threads.
