Well, I am nearing the end of my tww and have come to believe it hasn't worked. Pre-AF symptoms right on schedule with her due Fri or Sat depending on how she feels. I feel exactly the same as a previous couple of cycles so now its just waiting for the inevitable it seems. As the HCG shot wore off, all of my hopeful symptoms just faded away.
Will let you know the final outcome but I was really glad to have somewhere to come and share and to see some wonderful bfp's while here.
