Normal Heartbeat for 6w3d??

We had an ultrasound done Monday and our baby was 6w3d at the time. The heartbeat was 104bpm. Now, I’m curious if this is normal or something to be terrified over. I haven’t had issues sans morning sickness. Everyone else seems to be getting heartbeats up into the 120 range. I saw that the “normal” should be between 95-110 and and just curious if that’s been the case with others and their little beans heart started going quicker around seven to eight weeks. My next appointment isn’t until May 4th where I’ll be 9 weeks.
