Hi, I'm a little late to this thread but I'm currently going through my first cycle using donor eggs so I thought I'd chip in.
We've been ttc for 4 years in total. We've had 3 cycles of own egg ivf and one FET - the FET resulted in a positive test but I miscarried.
Our embryo quality was middling, not brilliant, not awful but due to our ages (me 40, DH44), we felt that the quality wasn't there, the clinic said we could continue but our bank balance wasn't happy!
We did loads of research into donor conception, the impact on us, any child we might be lucky enough to have, our extended families etc.
The Donor Conception Network website has been a great resource - especially reading the thoughts of donor conceived offspring who are now adults, although most of them are the result of sperm donors and some struggle with the large number of donor siblings they have - not as much of a problem with egg donation.
It's a really personal choice but we decided to use a UK clinic so that any children we have will be able to find out who the donor is if they want to when they're an adult. We've also decided to be open from the start (if we're successful!), there are age appropriate books you can buy to explore the story together - I read loads of examples of parents telling their babies about them being donor conceived before they can really understand - whilst changing nappies etc, so that they can 'practice' talking about it out loud and means the child just "always knows", the same way, I've "always known" my mum and dad are my biological parents.
I reconciled not having the biological link when I read up on epigenetics - there seems to be early research that the uterine environment influences which genes are switched on/off so during pregnancy, "I" would be shaping who my son or daughter is, that's even before my influence in being their mother day to day.
We chose frozen donor eggs so I didn't have to sync my cycle, it's been a bit easier than a regular ivf cycle as there's no egg collection. I've had to inject myself with buserilin daily to stop my ovaries from doing anything, then take oestrogen tablets to build my lining up, that's it. I've started the progesterone pessaries this morning, and I will have to start intramuscular progesterone injections but that's not something everyone does.
We chose a 2 cycle package so we paid £14000 for 2 cycles, if we're unsuccessful, we'll get 50% of that back. We'll see if the gamble pays off.
Whatever you decide to do, good luck. I really hope you get the family you want.
