Ultrasound!

Brianna
So today was my first appointment, I'm 6w5d. I didn't get an ultrasound done. My Doctor said she will do a fetal doppler for the heartbeat at my next appointment but if we don't hear the heartbeat she will do the ultrasound but if we do hear it she won't do the ultrasound until I'm 20wks! Is this correct? I'm super upset I didn't get one done! HELP!!!!
