SO - long conversation with the Consultant again (who I think is brilliant) and he says he's been looking at the embryos throughout the day - 2 are starting to form a cavity, so look like they'll be good to freeze tomorrow.
I thought the cavity thing was bad when we spoke earlier, and that it meant we were losing those 2 guys - turns out they're developing faster and better than the others who are all still doing their thing, so it's still everything to play for.
Basically, we're going to sit tight tomorrow - speak to the embryologist at lunchtime and see how things are cooking and the numbers that are being frozen. On Sunday (Day 6) we'll speak to the consultant again and see how it's all going with the remaining ones - and as they do a Day 6 transfer we could do one then OR freeze the others too. I think we'll just freeze them.
He's massively reassured me about the FET process, and I trust him. They're quite picky about the ones they freeze, and the failure rate at thawing is less than 1% at their lab so I'm cool (no pun intended) with that.
If it's better for me too to let my body get back to normal, then I guess it can only be a good thing all round.
Bit frustrating, but the upside is that me and DP are going to book a 2 week holiday to give ourselves a break...no idea where as we've spent all our cash on doing this but we'll make it work!
