I have just returned from a dating scan (I thought I was 8 weeks) and they said they could not find a heartbeat but could see a sack and yolk. According to the size she thought I was 5 - 6 weeks, and I have to wait for another 2 weeks to see if it is a viable pregnancy. I have had no spotting or bleeding and although I have not been sick, have been very tired. I will go out of my mind waiting for 2 weeks. Is this normal to be so far out on dates when I do have regular periods? I feel very sad that it does not look good.
