Anticipation is killing me

I am 7-2 with my first child after trying for 1 year.  My Obgyn wouldn't give me an appointment until I'm 9 weeks. I barely have any symptoms other than sore breasts and a little fatigue. Part of me doesn't believe I'm pregnant. I can't wait to see my little bean on the screen. I just want to hear the heart beat so I know it's real.
