I don’t feel pregnant anymore

At the beginning my hormones were going crazy, I had a lot of symptoms. I got to see the baby around 9 weeks and everything was great. There was a heartbeat and baby was wiggling a little. Now I am 12 weeks and I just feel like my symptoms have gone away. Is this normal? I can’t help but worry i had a missed miscarriage. Maybe a fetal Doppler would help? I don’t feel the baby yet so I just feel like I am normal and not even pregnant anymore lol. Anyone else?
