lol Cass, I suspect my doctor. too , lamented me ever finding the internet!

I find doctors tend to be much more leery of doing a blast culture if you don't start out with many eggs. I have never had more than 6 embryos fertilise, and my doctor kept discouraging me from blast transfer, saying there was a chance I wouldn't end up with anything to transfer.

But hell, I'd done all the other rounds previously, and I needed to know if any were surviving to blasts. It came down to me being fed up enough to take the risk that we'd not end up with many, if any. Many clinics now do blast culture as standard procedure, anyway, so the success of them once you get to transfer must warrant the use.

Good luck and please do keep us informed. And if you feel like a chat, join in the monthly forum where those who are in cycles - or are waiting - try to keep each other sane.
