W1, we've been feeling a bit the same. Somewhat despondent after the two failed cycles and DW worrying it's an implantation issue. If it helps, one of the ladies who has just joined the thread I mentioned above told us tonight that she had success with her second FET, after failed stim and FET cycles.

It really is a roll of the dice as to whether a perfect embie will implant. Try not to get too ahead of the game and just go with the bad feelings you are having now. They do lift in time.
