hI silvia and welcome to HCM. Most ovarian cysts are benign and cause symptoms you ve mentioned when become ruptured or torsioned or when press adjacent structures. Malignancy is the last thing to be considered but it musnt be unrecognize. Best whey is to d CA 125, follow its size, and do laparoscopic exploration with biopsy. If CA 125 shows abnormal values you must be admitted to hospital as soon as possible. If not, then you have time to wait your gyn work up. Wish you good health.
