Scan advice

Emma
How are people getting scans as early as 6-7 weeks. I have had two Mcs since my son was born and 1 before him and am currently at 6 weeks. Everything appears to be going well but it's early days. My first mw appointment isn't until I'm 9 weeks and that's just a simple check up at the docs. I assume that it's a country thing, I'm in the UK. Can I get it a scan privately to see that everything is going ok? Thanks and best wishes to you all x
