Pain in my lower right side of my belly

Molly • A London girl 🇬🇧 who will tell you anything you want to know.
Okay so every now and again about 7ish days after my period I get this pain in my lower right side of my belly it's right next to my pelvic bone and I know it's not growing pains. I wanna know what it it or if I should go to the doctor. What's your opinion? Do you know what it could be? The pain is Inbetween my fingers but it spreads upwards as well 😭😭
