Crossing everything for you. I had to have a scan last week (suspected ectopic) and had the same result. I figured I was bang on 5 weeks, they reckoned 4-5 weeks. All we could see was the sac..but at least it was in the correct place. I've to go back on Monday, when I reckon I'll be 6wks and 4 days. Hopefully we'll see something more then.
