POSITIVE! What now??

Lu
So I tested positive (did 6 tests just in case hahaha!!!) a week before AF was due. I still have to wait until the weekend to technically "miss a period", do I wait until after then to book a Doctors appointment? Or will they see me regardless? 
Will I then just have to wait for a 3 month scan to confirm it all? (i'm in the uk) Can I ask for an earlier scan?  
I'm so nervous! Haha
