12 weeks today!

How is everyone feeling, Or felt around the 12 week mark!? We have decided against any abnormalities screenings so no 12 week ultrasound for us. We heard the heartbeat 2 weeks ago at 10 weeks and it was 181! Still two more weeks til we go back to the doctor to hear it again! I have been very fourtante in my pregnancy, and haven't had any symptoms, still without symptoms just slightly sore breast and that has decreased a lot. I constantly am
on edge that I don't feel pregnant, and worry something is wrong. (First time mom probs?) Anyone else experiencing these feelings!?
