Hey Sally,
WOW! I just presumed it would always be spot on....but I guess there are so many variables that can go wrong when you are charting.
I need to remember that it is really only a guide.
I just get so stressed about it. We have just hit our 6th month of trying and this week I am having a really hard time about it. I mean I knew it would take time and I am trying to be positive but sometimes you just want to scream!
SOrry for the vent.
