If it were me I would tell my Doctor. I can't guess what it is but it sounds painful. I use to have pain when I ovulated. Sometimes I would be doubled over. In my case a medication was causing issues with my ovaries. I got off the medication and the pain went away.
Although nothing's impossible, based on what you said it doesn't sound like you have PCOD. Women with PCOD typically have irregular menstrual periods, elevated androgen levels (excessive hair growth of the face, etc), and are often overweight. Given the information you provided, I'm not sure what exactly it is either but there clearly seems to be some nervous involvement (radiating pain).
