What to expect at appointment #2

So I have my second appointment on the 24th and they didn’t really tell me what we’d being doing at the appointment. My first appointment was just a viability ultrasound and the doctor was in and out pretty quick. I’ll be 11 weeks exactly on the 24th. What do they typically do at your second appointment? Will they do an ultrasound and or check the baby’s heart rate? I’ve just had a little bit of anxiety because someone I know went back for their second appointment and there was no longer a heart beat. I’m terrified of that happening to me but idk if they will do anything to at least check on the baby at my next appointment
