Ovarian cyst surgery

kb

I have been having some pretty wicked pelvic pain for an extended period of time. It started getting bad mid march. I finally just went to the doctor (finally got insurance) and they found a 12 cm cyst on my left ovary. I'm so overwhelmed and scared. They mentioned removed my ovary because of how big the cyst is. Can I have some insight? Is surgery the only way to remove? Has anyone had issues TTC after surgery and removal of An ovary?
