It sounds like you are dealing with a lot. i don't know what your financial condition is but would you consider a surrogate? Apparently many women who have had such issues use their eggs and partners sperm but have a surrogate carry the child. I do think it is probably very expensive though to find such a person. Do you have any really close friends or sisters who might offer? I know it would be a lot to ask of someone as they would basically have to give up their lives for 9 mos or more.
On the other hand, have you googled t-shaped uterus on the internet to see what you come up with?
Where do you live and do you currently work with an RE you like? What does the RE say?
I hope that you can get this issue resolved..
