16 weeks and confused

Bee
Okay so I went in for my 16 weeks appointment and I didn't get an ultrasound just blood drawn and I got to hear the baby's heartbeat on the Doppler. Has anyone went in and didn't get to see the baby? I don't like it at all its been a month and now I have to wait another month what if the baby is in distress how would they know? It just didn't seem right idk
