Can a ovary go from being 6times the size it should be from still being enlarged but not as big as 6x?

I had a ultrasound scan about 2months ago because i had 3 water infections and was blood in 1 infection
lower back pain
irregular bleeding
swelling of my (tummy)
pain during sex
excess wind
weight gain etc my leg also goes numb

My new doctor was worried and sent me for another unltrasound the lady who did the scan this time gave me the impression everything was ok and normal but would send results to my doctor

my first ultrasound scan surely the nurse couldn't of got the measurements of ovary size 19.3cm wrong ? then it go to normal? because she would of double checked something like that right? ....

Is there anything that can make ovarys enlarge and go small again? i know your gunna advise me to wait for my results but im worried this is going to be over looked now

also is it normal to have a dark round shape in your ovary? this came up on the scan and she told me it was normal?

i also have borderline polycystic ovaries and lots of follicles

thankyou
