12 weeks don't feel pregnant

Hey all,  I am 12 weeks 5 days and I don't really feel pregnant. All my symptoms are gone and besides being a little bloated I feel nothing. Getting really nervous since this is my rainbow baby. I had an ultrasound at 11 weeks 6 days and everything was fine. We told close friends and family but I'm scared to tell others incase something happened. Anyone else feel this way?!
