Living in hope!

Hopefully someone will be able to help, I’ve had a few early miscarriages so after trying for 2 years we gave up. Found out I was pregnant a few weeks back so doctor sent me for an early scan. By my dates I should have been 8 weeks but scan measurements showed I was only 6 weeks and 3 days. They done an ultrasound and internal scan but no heartbeat. Back in 7 days to see if there’s any development. Anyone similar success stories? Going out of my mind!!!
