Thank you to everyone for your lovely messages. rum keeping fx for you tomorrow, sure everything will be fine. Calling glad to hear that all went well for you too.
vivi we had IUI at our local NHS-linked fertility clinic (we were private patients), who were awesome. We got pregnant on our second round, but the clinic said that this was pretty good going and anything up to 4 or 5 cycles would be fine (just like anyone ttc naturally). We do like the idea of DW carrying a second child, but don't want to make a firm decision yet as it will depend a bit on various factors, including how this pregnancy goes! Ditto with the donor. We haven't gone with exclusivity or anything like that, but we still have some, ahem, what DMiL refers to as "ingredients" in deep freeze, which we can use for the next time.
Good luck to your friends, it's always nice to hear of other people in a similar situation to us! We never cease to be amazed and delighted at how much more common and normal same-sex parenting has become in the last few years.
We've attached the thumbs-up from our DD (haven't got used to saying that yet...), we think it's the cutest thing in the entire world, but then we would, wouldn't we?
