Scooby, me again... I seem to be following you everywhere at the moment!

I think if you're worried about another ectopic, then the earlier the better - keeping in mind that it may be too early to detect a heart beat and you may need to have a follow up scan soon afterwards.

That said, I had a scan at 6 weeks and 3 days (yesterday) and saw a lovely heartbeat blinking away at me. It will all depend on the equipment your clinic has, and whether they are going with an internal scan or not.

My FS used this site to give me a run down of different dates that I can expect things to happen - according to those calculations, a heartbeat shouldn't have been detected until the 30th, but we saw it on the 26th. With my first pregnancy a heartbeat was detected at 6 weeks and 5 days.

I think you'll be fine with the earlier scan.
