baby moved at 10 weeks

A

the other day I went for a ultrasound it was transvaginal I got to hear my babies heartbeat for the first time it was the best thing ever than as we were looking at the screen the doctor says omg the baby is already moving it was just a slight movement but it was amazing the doctor was saying the baby usually doesn't start moving that early, just wanted to share my first experiance and would like to know if anyone else has experience this
