Rainbow baby ultrasound worried

Based off of my LMP I should be 6w5d due to pcos I take metformin and do ovulate later/have long cycles from time to time I called my OB today to schedule another blood draw and they had me come in for an ultrasound instead, so far my HCG levels are

11/14 57

11/16 155

11/23 3979

11/24 5923

The ultrasound felt fairly rushed we saw yolk sac and gestational sac, not much was said to us the tech did mention to the other tech in there that the gestational sac was measuring at 5weeks and that she saw something that she assumed was baby but we didn’t get to see much, I had a early miscarriage in April I won’t hear back from the doctor until tomorrow. Should I be concerned?
