Well we got a BFN today. We can't do it again so that's it for us basically. Its been a hard four year battle which we haven't won. It's a horrible, horrible feeling. We are going to plan our wedding now and get on with our lives together childless. Good luck to everyone else who is going through the very stressful and emotional ivf journey. Thank you to everyone's advice and support. This is a really good website for that.
