Size and Heart Rate

Hey ladies! I'm 6 weeks and 4 days today and we had our first ultrasound yesterday! We got to hear our little one's heartbeat for the first time and what an incredible sound. The doctor afterwards told me she was measuring small and that her heartbeat was a little slow. I was just wondering what everyone else's first ultrasound measurements were.

Our baby is currently .41cm long with a heartrate of 104. Research I've done says these are fairly normal measures. What do you ladies have?
