A.M.
I think that the days that you have to wait until you can take a pregnancy test should count as a week each! I understand how crazy the waiting can make you. All of your symptoms could be easily explained as pregnancy, or as a eager mommy anticipating the possibility of pregnancy. It's hard not to get your hopes up... I know.
I never experienced actual pregnancy symptoms as early as what you are describing, but I really know the mental preoccupation and intense emotions you are going through. Particularly with my second pregnancy, I felt this way. I took one of those '4 days before your last period' tests, which turned out very faintly positive. The next morning, doubting my good fortune, I took another test, which was negative. With my emotions careening out of control, I took a test each morning for the next 2 days, both of which were negative. I was so sad, figuring I'd gotten a false positive. Turns out, the next day, the test was clearly positive, and now my little Guinevere is 2!
Anyway, I don't know if this helps, but I want you to know that you aren't the only one who goes a little nuts during this intense time. Hang in there!!!!!
