Ovarian cysts...symptoms?

For those of you who have had a cyst on your ovarie(s), what were some symptoms you were experiencing? Bloating? Back pain? Cramping? And how was it determined you had a cyst? Ultrasound?

I’ve had pain that seemed to be caused by a kidney stone but when they tested for a stone there was no indication..a CT showed a mass but unsure of what it exactly was..I going to see my OBGYN tomorrow and I’m a little nervous.. just trying to see if it could be a cyst!

Thanks !!
