Really odd pain. Help?

5 dpo I experienced an extremely sharp pain in my right side. It felt near my ovary but not exactly my ovary. It took my breath away and made me hunch over for about 20 seconds then it disappeared. This was Friday night. Now, I am having trouble sleeping and getting comfortable bc my uterus HURTS! It feels like every time I bend over or lay a certain way in crushing it. It's tender when I palpate it but it's not cramps. Dull, achy, heavy, and sore. Anybody have any idea? I've never had cysts or endometriosis or anything like that but I do have a retroverted uterus.
