Want to scream

Eri
AF is late by 6 days which hasn't happened ever-- it's always on time! Dr did all the blood tests and they were all BFN. I just want AF to come already so I can start my cycle over and try for a baby again. This is the worst feeling because nothing is happening and just feel stuck and helpless. :( This coincidence of my cycle being f'ed up RIGHT when I'm TTC is brutal.
