I'm sailing in the same shore as you are! AF was 01-02-06 and I have the identical symptoms as you do, its so weird!

I also have an increase in appetite, my entire family has noticed! And you talk about sleeping! I've literally been in bed since Friday! I only come out to go potty and eat!
I just wanted to let you know that you are not alone! I'm sending loads of baby dust your way and please do the same for me! AF is due next Sunday, I hope she misses her flight and has a 9 month lay over!
