Early ultrasound

Br

I had my first appointment this morning at 5w4d. The arrow is where baby was and the circle is the sac. So we could see the flickering of the heart but he wasn’t able to get a good reading. He has me coming back in two weeks to hear it. I always think the worse but him not being able to read the heart beat waves I’m guessing makes me all sorts of nervous. Anyone else had super early ultrasounds like this?
