Not feeling "pregnant"

Anya
Outside of tender nipples...not much nausea at all....& slightly tired. I'm just so nervous this time. I don't know why. This is my 3rd baby, never had a miscarriage. My 2 previous were boys and I was SUPER sick the ENTIRE 9 months with both. So this is way different for me. I'm 6w3d, due 9/11. I go for my 1st sonogram on my birthday 1/27 & I am SO anxious just to see baby and heartbeat. Anyone else not really "feeling pregnant"?
