Should there be a heartbeat at 5 weeks?

Julie
I'm currently 5 weeks and 6days. I had a vaginal ultrasound today and there was nothing. No heartbeat. Just the gestational sac. The lady that did the ultrasound said that was normal and it was too early.... 
Can anyone reassure me that what she told me was accurate?
