Hi Rhylis i had a mc @6 weeks in July this year so am totally understanding your anxiety on this one as ive just found out im pregnant last week (just waiting on bloods back on wednesday to see how far along but wouldnt be less than 4 weeks)
I agree with @nelljm doing a POAS is a great help and is reassuring. As soon as i got a an immediate BFP yesterday i felt a lot more confident in this pregnancy.
Im in the same boat as you, went to my scan..nothing there so getting past that first scan will be a bit of an acheivement,and will help greatly in being able to focus on a happy healthy pregnancy.
