oh hun,
i am so sorry to hear this news. this TTC thing is so hard and i think especially when you have done IVF cycles. if you need to chat just PM to let me know or anything.
my heart goes out to you and your DH. you didn't do anything wrong hun, you know that, but it is so hard to find understanding in the unexplainable.
give yourself the space to grieve and use BB to vent etc if you need to. there are many here that understand your pain and anger and can give to you.

:hugs:
