why don't I feel pregnant?

Brianna
I'm 8 weeks and 3days, and I don't feel pregnant hardly at all. 
I had a bunch of symptoms around 7 weeks, but they all of a sudden disappeared. 
Called my midwife and she said everything sounds normal and symptoms can come and go. Did think it would be worth it since we had any ultrasound at 6 weeks (I was in a car accident and wanted to check on viability), and they heard a heartbeat there.
Any input on this? Anyone else notice symptoms gone for more than a week and then they came back/baby was fine? 
Any peace of mind would be great- this is my first baby and it's making me stir crazy since I have about 2 and a half more weeks until my next appointment.
