Frustration when you know something but cannot get it confirmed!

I am know I am pregnant at this point. There is no mistaken it. I have officially missed my period. I am feeling sick when I do not eat right away. I am tired all the time. My legs ache. Why won't a test show what I know? Who knows. Hopefully tomorrow I take one and it does. Ugh!!!! I just want to tell the world but can't til my test comes up. My fingers are crossed for tomorrow. I know I am without a doubt. I think I am sure it is not in my head. I cannot wait to confirm out baby #3.
