6wk heart rate low?

Terra • Married💍12.15.17🤱🏼Momma to a 🌈 baby girl

I was told my babies heart rate at 6 weeks exactly is too low (Hr was 96)... I conceived 3/22, the ultrasound was 4/19...i don’t get how that puts me at 6 weeks or why they think it’s so low? Should I be concerned? What was everyone else’s HR @ 6 weeks? #firsttimemomfreakingout
