What do they do at your appt?!

P359382

Had my first appt with my OB when I was 6w,4d on 7/21/17. Got my ultrasound and everything was normal and baby's heart beat was 131. I'm scheduled to see my OB now every month but not scheduled for another US until October. Will they be checking baby's heartbeat at my next appt?! How will I know baby is still growing and okay if they aren't doing an US?! I know stupid question, just nervous.
