Hello, and I hope I can help you today. Unfortunately your situation is complicated because you have multiple conditions that can all cause similar symptoms. In addition, problems with your colon can also cause pelvic pain. Even though you are on oral contraceptives, there are types of ovarian cysts that can develop independently of hormonal conditions. So it really is not possible to discern what the cause may be without at least an ultrasound examination of your ovaries and a test of your urine. I suggest you see a local OBGYN doctor for evaluation of your symptoms to help you feel better as soon as possible. I hope this information was helpful, and with proper medical care, I am sure you will feel better soon. Best wishes, Dr. Brown
