@MarchAprilDecember oh you poor thing, asking to wait for 2 weeks is horrendous. My EPU only had a 1 week wait between scans. And it was the dating that threw me off too, at 6 weeks they measured me 5 weeks which didn't make sense but at the time they seemed positive. Bleeding started 4 days after that first scan. From what I read online during this time, it could go either way for you. I've read many stories of women in the exact same position and to their shock the next scan showed a growing baby etc. Likewise many people, like me, have it ending in bad news.
If I were you I'd be inclined to go for another private scan next week to break up the wait, or contact EPU again if anything changes in regards to pain, bleeding etc.
I will say this though, the waiting to find out was truly the worst part. Once we had it confirmed, yes it was sad but it was a relief to just know and start the process of grieving and moving forward.
