Thank you all for your responses!
I feel a bit better about the whole thing..and still a little hope for my last embryo! Let's hope it's a lucky one!

TT40 - I hope that I am like you to get my BFP on #5! Are you thinking of trying again?
RhiChiChi - I really hope that my lap works some sort of miracle! How long were you trying before having your lap? The frozen embryo should be just like having a natural one in there providing it all thaws ok - which all previous 4 thawed perfectly... I was lucky enough to get photos of the last few at 4 cell stage
vic261- The dreaded 2ww!! Oh how I hated it sooooo much! Google was my best / worst friend at that time! How are you traveling? When is your blood test? I have everything crossed for you! I thought I had come across everything imaginable on google so far, but had not heard of the pipelle biopsy - sounds def worth trying that's for sure. I'm at the stage where I am up for everything and anything!

Thanks again for your replies, it means a lot - saves me from going nuts. I had been trying to have a 'surprise' for our families etc by not telling them, as I just expected that it would work first shot and be that easy! After 2 failed attempts, I ended up telling my parents. I really struggle talking about it in person as I just start crying - & I'm not an emotional type of person (well in front of others anyway). My partner's family and my siblings still don't know.
My brother and his wife just announced that they are expecting.. I am deep down happy for them, but it is so hard to bring that to the surface! I feel so guilty that I cannot be over the moon... I just keep comparing myself, if that cycle had of worked, I'd be due around the same time etc. So terrible and makes me feel like such a bad person! Is this at all normal or do I need to pull my head in!?

Thanks ladies
