UK LADIES... HELP PLEASE??

So I am 5 weeks pregnant had a MC last year and I'm at high risk of an ectopic pregnancy due to having PID in 2014. I am desperate to get an early scan to make sure everything is ok and it's not an ectopic. I know they wouldn't see much before 7/8 weeks but I'm petrified. Does anyone know how I would go about trying to get an early scan? Last time I had a scare it was an ectopic and they did an early scan cause I went to a&e with pain in one side and I was only 5 weeks but they saw the sac... I did end up losing it a week later. Anyone have any ideas?
