I don't feel pregnant...

Lisa
Hi ladies,
According  to the first day of my last period, I am 5 weeks 3 days pregnant today. I found out I was pregnant a week ago exactly.
This is my first pregnancy; this week alone has been a long one. It has been full of lots of emotions! My husband and I are both very excited. I am also a little anxious, because I want this pregnany to last. 
Being so early, I realize that you shouldn't be able to physically see that I'm pregnant yet. I've experienced some minor moodswings (crying mainly), light cramping, and being very tired. 
I know that for the majority of what is left of my pregnancy I will begin to feel and look pregnant, so I shouldn't complain! My first appointment is July 22nd. I am anxously waiting to make sure "something is actually growing in there." I just can't belive it, even after taking 4 positive pregnancy tests in the last week (just to make sure). I want proof!
Am I the only one feeling this way? It's an exciting time! I am just hoping for the best :)
