hi everyone. I had my first FET today with a 4BB blastocyst. I am 44 and have had wildly varying percentage success rates from doctors, nurses, the embryologist and good old Dr Google! Trying not to get hopes up too much as the 9 day wait for my blood test will be unbearable if I do, but wondered if anyone has been in the same boat and can give realistic chances. We have one more in the freezer but it is a 4BC. Thanks
