do i have endometriosis?

jordan

so i got my period first in 7th grade, around my sophomore year i started to get very bad cramping where i couldn’t move and i would throw up for days when i got my period. i started birth control and the puking went away, i have started to notice over the past few years very bad abdominal pain with tampons in and during and after sex. i’m not 100% sure if this is endometriosis but i would love some help and advice, thank you!
