Don't know what to do. Opinions please!!

I am having a sharp pain in my lower belly about in the place over my ovaries. It feels like a rubber band being snapped. It started last week when I stood up and now it happens an hurts more frequently esp after sneezing or coughing and sometimes standing. It's painful enough it double me over an I have a pretty good pain tolerance. I do have PCOS. What do u guys think it could be?
