Hi hun. I had this in tri 1. had a scan at 7 weeks and got put back to 5 weeks and then had to wait another 2 weeks to be scanned again!! don't stress too much, I was told that just because they date you from the first day of your last period that is just a rough guess and baby could have implanted anytime up to 2 weeks after. it doesn't mean baby isn't there. I had lots of dark brown CM so I pretty much convinced myself it was bad news and now here I am in tri 2 at just over 14 weeks! good luck xxxJust had a 6 week scan and told that have a growing yolk sack but nothing else. Have to go back in 2 weeks for another scan, it doesn't look good though. Anybody had this before with a positive outcome?
