I had Complex Hyperplasia Atypical. I was given the Marina too. I've never had children, so I went into contractions. My body wanted it out and pretty much tried to deliver it. I was supposed to have it for three months, but it was kept in longer (about 6 months). Despite the pain, Marina did it's job and I am now Complex Hyperplasia Atypical free. I' presently moving forward with expanding our family. This has not effected my fertility.
I've been reading about your case and it seems to be complicated. Have you thought of a seregate mother or adoption, if the hormone therapy is not helpful. I have attached a link that might give you more information. Wish you the best of luck!
