Referred for a vaginal scan!

Hi Everybody.

This is my first post. Wasn't sure weather I should post or not. Anyway I'm petrified! I went for my routine smear on Friday 4th, the nurse took my swab and said she is referring me for a Colposcopy as there is an abnormality on my cervix. (I've already had a Colposcopy 6 years ago) Loop results from that were CIN1,2&3 clear margins. My last smear 2017 was negative! Today I got a call from the hospital to say I have an appointment for a vaginal scan on Saturday. Has anyone been for one of these and what was the outcome. I'm so scared! I don't know what to do and don't have anyone to talk to that understands.
