Hi JennyH1,
I'm sorry for your struggles. I can't advise, but I do sympathise. We've just ended x3 rounds of OE ivf with only 1 viable embryo which was frozen and came out of the freezer with 50% cell loss. We were told that we had a good chance of pregnancy at the start of all of this.

We're now looking into DE and it terrifies me that we'll suffer in the same way again.
I guess there's just so much of the unknown re ivf that as much advice that someone can give you, it just might not be right/relevant for you. I know finances are certainly a restricting factor for most people going through ivf, but if they're not for you, Instituto Bernabeu in Alicante offer a pregnancy and childbirth guarantee. They do charge astronomical rates - 18,000 euros, but they give you your money back if you don't have a live birth. I'd certainly go this route if I could afford them as I'd feel much more reassured that it was going to happen.
