Empty sack

Cat

Went for an early scan today as I thought I was nearly 8 weeks and due on the 2nd of July according to my last period date! Midwife said I'm measuring around 6 weeks and all she could see was an empty sack and I have to get rescanned in 2 weeks 😭 now I'm panicking and this is going to be a horrible 2 week wait! Anyone been through this before?x
