I tried everything this sway too, it is my second time to sway and I did total opposite. My FF charts for my last two pregnancies are so different, my diet was so different. I actually draw comfort from the fact that we really did try so very hard. I also prayed and prayed.
I understand exactly how you are feeling right now :(
I was so sure this time would work, I was also very excited (secretly) to feel we were going to get a little boy this time :(
