Long but important about ovarian cysts

Rylea
So I had to to an ultra sound on my ovaries(vaginal and stomach ). The results said that I had multiple cysts on each ovary but that's there's something over a centimeter big on my right ovary that they don't know what it is. I now have to get another ultra sound to see if they can figure it out. Anyone else experience this? I have constant cramps and lower back pain, I'm just nervous as to what it is now!
