We had more great news today - it's really quite unbelievable and I keep having to shake my head - day 3 embryo results - 7 x 8A (absolutely perfect) and 1 x 7B (a bit behind, but crazily we would have used this one on any of our previous 8 cycles, and this time this one won't even get a look in!!).
They did assisted hatching today in preparation for transfer on Wednesday (which probably was needed for my old eggs, but probably not actually necessary on these eggs, but done now). So it kind of looks like that old eggs were equally at fault as MFI issue.
Anyhow, we're hedging towards transferring just 1 embryo - I like the idea of twins, but personally don't like the risk factors, premie births and difficulty carrying them when I'm not super fit, plus thyroid issues. On a side note my FS also rang to say that even though he's increased my dose of Thyroxine, my TSH still hasn't gone below 4 (which is only just a tad higher than normal range). He's never worried about it before in my previous cycles with him, but I've read recently that now some FSs like TSH to be below 2. So he's increased the dosage again. Has anyone heard anything about Thyroid levels and implantation?
