I had an early us at 5+1 and all they saw was a very small sac and yolk sac. No fetal pole. Us tech said not to worry because most of the fetal poles don't show til 6 weeks. At our 10 week us we saw a healthy baby. I'm now 15+3 and growing
4 weeks is very soon. I honestly think you are ok! Have them check in a week or two!
