I've had two scans done so far, at 6 weeks and 8 weeks. Party because I had some bleeding and a pain in my side, and I had to travel, so we needed to rule out an ectopic pregnancy. But the 8 week scan was really more to reassure us that everything is going fine, even though I had been spotting.

It was for me an immense relief to know that things measured out as they should: the diameter of the sac and the heartbeat at 8 weeks and so on. So I can relax more, and my husband is showing all his mates the photo of the 8 week ultrasound - yep it's a blob!

For me it was totally worth it to have an early scan done, even two of them, just for the peace of mind. No doubt other people's experiences will differ, though.
