Extremely Anxiety Provoking

I had my anatomy scan Friday the 5th. I was told the ultrasound tech couldn’t get a clear image of baby girls hands so they are bringing me back for another ultrasound, but she is sending me to a fetal cardiologist for the heart imaging! If she couldn’t see the heart she would just look when she looks at her hands not send me to a specialist unless she saw something or didn’t see something, she would bring me back in hopes the baby is in a better position same as she is doing for her hands. Has anyone had the anatomy scan done been referred to a fetal cardiologist and everything has been fine. I am worrying myself to death literally!!
