Get checked: If sounds like you need to see your GYN to get this checked.

Need to be seen: Your symptoms may represent acute appendicitis and I would recommend calling your primary care provider or go to the emergency room to determine the exact cause

Get examined: If your having abdominal pain it would be advisable to see a physician rather than try diagnose yourself on the internet.
