Period? Ovary cyst?

Madisonbedard

Hi ladies! I’m 18 and stopped taking birth control because it was making me feel off. I just got my period without being on it and I’m in a lot of pain. Right side my mom thinks it’s a a ovary cyst and I hope it is and not my appendix. If any know symptoms or if it’s normal let me know!!! Help a girl out!
