Hcg levels too high??? Help!

Sadie

Just had an early scan and my dates put me at 6+1. They saw the sac which they said was good but couldn't see anything inside. They explained that that was normal for 6 weeks. They did my bloods etc, but they just phoned back to say my hcg levels were too high and they should have seen something in the sac 😕. Anyone else had similar?? My brain is jumping to all the worst conclusions! My next scan isn't until Monday so I've got the entire weekend to panic 😔 xx
