Side pains

Cree • Dog Lover 🐶 Avid Reader 📚
Guys I need some help with something! For about two years now I get these really bad side pains. The catch is though, they happen both when I'm on my period and when I'm not. Sometimes I'll break down in tears crying it's so painful. Now I say 'side pains' but it feels as though it's either my ovaries or directly over them. I've been to my doctor about it and even had an ultra sound done, but nothing came back from it. Do you guys have an suggestions on what it could be? Sometimes it's just one side And sometimes it's both. It's really starting to freak me out considering mom doesn't believe me anymore
