I had a dating scan at 7weeks and 6 days as I had no idea how many weeks I was as I have pcos and don't really get periods. You should ask if you can have one I'm sure they would say yes. With my first pregnancy that ended in a miscarriage they gave me a picture and I wa 5 weeks it was just a sac with the feral pole in it.
I had my first at 8 weeks. I think 11 weeks is better though because you can see a more developed fetus. Might even get a peak at the gender?
With my 7.6 weeks scan all you could see wa like some little alien with tiny tiny arms and legs. I wasn't offered a scan photo and I didn't ask as It was uncomfortable as the sonography nurse didn't speak to me the whole way through x
