Hi zap, sorry to hear that AF has showed up...it is hard to cope with the dissappointment...as I've been there...

Don't give up hope and that 1 snowbub could be just the one to give you a BFP, I say that because that's what happend to me. I was devasted when my 1st Stim cycle didn't work, my AF show up 4 days before the b/t, so I didn't even stand a chance to get my hopes up at all...then my one and only frostie the following cycle gave me a BFP!!! And it seems girls here have been having lots of success with FET, and there were 3 of us all got BFP on a FET cycle that month!

So don't give up hope, this little dissapointment might just be the pass to be successful next time around. Hang in there and good luck!
