Exhausted.

I don't understand it. I'm exhausted. I'm getting enough sleep...I would think that going to bed between 9:30 and 11:00 each night and getting up around 6:15-6:30 would be sufficient rest for me. I tend to do best with 6-7 hours of sleep. If I get much more, I'm a grump for the rest of the day. Less, a zombie. So, *why* am I zombie-like today? And yesterday? And the day before? Should I dare hope that it's a *symptom* and that I'm finally pregnant? I haven't yet POAS. For once, I'm scared to. I am actually afraid to see a negative this time. I have one hpt left at home. I want to save it until I'm late, but I don't know what late is anymore. Is late day 27? Or is it day 32? That's almost a whole week difference, people. A woman can go crazy in less than that amount of time. I'll test Saturday (only 2 days from now). That will be day.........counting.........27. Wish me luck!
