Help: Unsure if I should go see a doctor or not?

So I'm kind of wondering if I should go see a doctor or not. Sometimes I get a sharp pain in what feels like my ovary. I only feel the pain when someone jostles me. So for example if my fiancé grabs my hips and thrusts me against him (no penis involved) it hurts in my ovary like a sharp stab. Well now I have that pain all over my lower abdomen. And when I sit down to pee I get the pain again. Could it just be that my periods late and so it's like affecting me? Or should I go to the doctor? But like what would they even do?
