Haven't had an ultrasound😞

Noemi
Ive had 2 appointments so far and on my last appt i was 10wks 3 days and doctor barely listened for heartbeat. Does anyone know around how many weeks i should be getting my first ultrasound im dying to see the baby😩🙏🏻 I have asked but all they tell me is they will call me to make an appt for ultrasound and nothing yet im going on 12 weeks now?
