6wks1d ultrasound!!! Normal??

Raven

I had an ultrasound done 4/25 and according to my LMP i should have been 7 wks exactly but my ges sac was reading 6wks1 day. The U/S tech only saw a ges sac and yolk sac. Is this normal? My next apt is may 8 and I’m praying to god i will see my baby with heartbeat.
