So much pain

Kayla

So my periods are terrible. They are 7-9 days long, I bleed through super plus tampons, and the cramps are blinding pain. I’ve asked my mom to go on birth control but she said she “doesn’t want to make sex easier”, but I am in so much pain. She also won’t take me to the doctor to see if I have endometriosis or fibrosis. Any advice on what to do???
