endometriosis

okay so i was put on the pill like a year ago for awful pms and periods and im still on it. like i would puke from cramping pain, i would bleed heavy for 7 days straight every month and, i bled so much till the point where i was anemic. anyways, i was just wondering if any of you guys have endo and experience the same symptoms because i am so lost. im wondering if i just have horrible genetics and was cursed with this or if i have something more serious going on that i should get checked out. if anyone could help that would be lovely, thanks babes<3
