chunky ovaries...

so I've recently been to my OB and they had to do an ultrasound on my ovaries (I've been having some pains) and found out that everything is "fine" and shouldn't be having issues ttc. well, she also told me the "average size" of an ovary is about 5cm..... mine is at 18cm+! she stated obviously we have to go back every so often to keep an eye on them because anything over 20cm isn't normal.... no cysts, no fibrous tissue.... I jokingly asked how I can put them on a diet... haha😂 but seriously anyone else have a similar problem? how hard is it and or what did you do to get that beautiful positive?..
