I have received a letter telling me I have to go to hospital for a colposcopy as a result of my recent smear test. The letter does not give any more detials than that, I have researched a bit on Internet and most people who have been referred seem to have details of why (CIN 1,2 or 3) but I have not detials! Has anyone else ever had this? Does it mean mine is worse than CIN 3 which as I understand it is cancer! I'm really scared. Have got to wait 3 weeks too. Sorry if this sounds over the top but I'm just really worried.
