Thanks Ladies for your replies..

I think that's the way I have to look at it BW. It really made sense what you said.. There are endless possibilities.. The whole TTC bandwagon was not called that because it was an easy ride!! Too many variables and way too many things have to go right in order for everything to work out perfectly!

Thanks for your replies. They are all helpful I think it was a shock to me that most of the embies didn't make it as I was comparing myself to a friend who had all of her embies survive and transferred and it was a bit of a shock to the system when that didn't work for me. A leason I have now learnt. Good luck to you all xo
