Advice please

I have had symptoms for about 1 year and recently had bloods done that showed ca125 at a level 66 I wasn't too concerned as I had this 3 years ago but not as high and scan showed adenomyosis. Anyway I had my pelvic ultrasound done today and it was only about 10 seconds in that she said do you mind if we do an internal scan. Now I'm worried that they have found something or is my mind working overtime? Any advice much appreciated
