HCG 19,000 - yolk sac no baby

I went in for spotting.

They estimate I’m around 6 weeks.

They saw the gestational sac and yolk sac but no baby...

With my son I saw his beating heart at 17,000...

Should I be worried?

They said my bleeding isn’t coming from my cervix so that’s good! I have a history of miscarriages.
