Some random info alert! Being in my Happy Bubble I didn't want to talk to Dr W about what my options would be if this cycle didn't work but considering I had access to him I thought I'd best take advantage.
I have one frozen embryo left. If I fly over for a single FET and it doesn't thaw well I wouldn't be offered an embryo from their embryo bank. They currently have a shortage of embryos because once parents have real life babies from their donations they don't want full siblings to be donated to other women so chose to discard the embryos instead.
My nurse didn't recommend using one of the donated eggs because they don't thaw well, to then be inseminated, and she explained the drop off rates.
Yes, @Blossom74 you can do an egg sharing fresh cycle with another woman. So splitting the costs between 2 women. Apparently you just need to be very clear about how to allocate an uneven number of eggs and how you both deal with it if your proven donor produces significantly less eggs than on previous cycles.
Dr W definitely recommended using my current ED again because she produces such good quality frozen blasts.
There's a lack of new sperm donors, who are recruited from universities, due to months of student unrest here. Long story, but CFC haven't been able to get into the uni's so had to cancel their latest recruitment drive.
