3 week mark

Yay its finally here, if im pregnant then I would be 3 weeks today. Another 1/2 week and I'll start testing till the 4 week mark which either means AF will come or I will be 1 month pregnant. I can't wait to know but at the same time I don't feel it either,I hv more of a feeling that it didn't go through and im not pregnant at all. I hv my appt set up and ready in case there is a problem then this will gv me a chance to work on it.
