Hon I went for a scan at 6wks and was dated 5wks - tech could not see any embryo etc but did an internal us and found fetal pole told us it could go either way - 2wks later there was bub bouncing away nice strong heart beat and he is now 6yo. I can understand not wanting to get your hopes up but thefre is no harm in waiting for the scan if there is a glimmer of hope. hang in there - hope you get some good news
