I am so sorry they cancelled your transfer but did they explain you can still have a frozen embryo transfer - they sometimes wait full cycle this your next period after this one ... so a months break or sometimes if you are okay they will do the very next cycle -so about months time if you are well enough.

You had a great egg/fertilisation result -congratulations.

Several girls from this forum have had it happen - and I know of several others - the next time with frozen embryo they got pregnant.

It is for the best though for your health but so very disappointing.It almost happened to me but I was okay (still didn't get a BFP that time)

We have a chat forum you can join in you want.
take care
