We had our first fresh transfer in March of a 4AB embryo which resulted in a BFP but an early miscarriage sadly. Our consultant says our best frozen embryo is a 3BB (he also said its a 10 which is the same as our 4AB, but I don't understand what the number means). I'm worried our little frostie isn't as good an embryo as the first so it's less likely to stick. Anyone have success stories with a 3BB or just any advice in general ?
Thanks 💜
