First U/S and heart rate question?

wed2be

Had my first u/s today t/v and saw the little bean... the heart rate was 130 and I am 6 weeks 4 days. I know this is asked a lot but could you please tell me what your LO's heart rate was and how far along you were. The tech said it was on the low side and of course now I am really worried. I researched it and am finding anything over 120 at 6.3-7 weeks is normal. Any insight?
