What does it feel like to have an ovarian cyst/other similar problem?

I woke up yesterday with terrible burning pain all around the area where I would usually have menstrual cramps. After vomiting a few times, I felt relief but still felt some pain in the cramping area. Today, I still the pain in the same area. At first I thought it may be appendicitis, however the pain is not as bad and I am not running a fever or other clic symptoms. I am right around ovulation time right now, could this be an ovarian cyst problem or something else related to ovaries?
