tender breasts? maybe?

since I began puberty (age 10. I'm 17), I will wake up with an intense pain in my rib underneath my armpit when I wake up. At first my family said it was growing pains, then maybe sleeping in a sports bra, but even when I sleep on my back wearing a loose shirt, I wake up with pain.

Could this be because of my menstrual cycle? or could this be a sign of something worse?

I know I should ask a doctor this but I've never had the same doctor twice so I don't trust them
