5 weeks 5 days?

Destiny

Hello everyone, I am pregnant right after a miscarriage.. I lost my last baby at 9 weeks. My OB decided to do early blood work and an early scan to see how things are progressing. My HCG is doubling properly but my scan is only a gestational sac from what the tech said. I think I see the start of a yolk sac but I’m so nervous to not see anything even though it’s early! I have to wait until the 16th for another scan to see if baby is progressing and the wait is killing me. Is not seeing anything this early normal?
