I have been diagnosed with ovarian cysts a few times in the past few years. But at this time in my life I think I have an ovarian cyst again but I'm not sure? I had my period 13 days ago. But this abdominal pain has been ongoing for the past week. I'm bloated, tightness and pain. And my ovaries hurt. I had an ultra sound and ct scan a few months ago. How do I know if this is an ovarian cyst? Why does it keep happening?
