Ovarian cysts?

Lacey
Can those of you that have had cysts tell me what your symptoms were? I got an iud 6 months ago and now I have an achy pain all over my pelvis, lower back, and sometimes my inner thighs. I've also only had spotting for a period until this month, now it's like I'm having an actual period so the pain could be from that also but I just really feel like something isn't right
