Hi sweetie 15 eggs is an excellent result that was the same number i got but only 10 of mine fertilised and then everyday wen the scientist called me a few more seemed to not make it, we ended up with 3 5 day blasties and 1 6 day blastie so a total of 4 which we were told was an excellent result. So dont be upset if you do loose some because thats very normal. goodluck with it all and fingers crossed. xxx
