Hi, I had some very light spotting Monday when I wiped. I was sent to EPU yesterday thinking I was 6+6 pregnant to have a scan . Scan showed a gestational sac only (no yolk sac or embryo) measuring 5+1. What does this mean? Am I miscarrying? I am confused. They took bloods to check HCG levels & nurse phoned to say they 'look good' at 2180. They will take more thursday to check levels doubling as they should. My LMP was 8th feb but we started ttc on 14th (very lucky to concieve quickly) so surely I could only be a max of 6 weeks anyway. I'm really trying to stay positive but it's so hard.
