I thought I was 5+6 today, and went for a private early scan as I suffer from anxiety and the waiting is awful. The scan showed a sac and yolk sac, and dated roughly in the early half of 5 weeks. No fetal pole or heartbeat or anything. Now I'm really worrying, is this normal? It puts me at around half a week earlier than I thought which isn't too bad I guess, but should there be a fetus at this stage? Does this mean I will miscarry?
