Why does my body hate me??

So this week has been hell of a week, I’ve been seen multiple times st the hospital and at my doctors for this pain in my lower right side of my stomach. Some doctors say it could be my appendix but today one said it could be a cyst on my ovary. Earlier this year I was diagnosed with PCOS and have been worrying about my ability to have children. But I need some reassurance.. if I have a cyst, does this mean I can’t have children? Does PCOS mean I can’t have children? Honestly if anyone has had similar problems can you pls tell me how I go about this? Can I get a fertility test or medication to help me get pregnant? I’m so confused as to why this has all happened to me and what I should do.. :(
