ok so i'm 16 and i'm worried i might have endometriosis. i don't know that much about it but some days on my period my cramps are so bad that i can barely walk. i've tried heating pads, pills, herbal remedies, everything! also (tmi) every time i pee when i'm on my period the cramps get worse. could any of these be signs of endo? should i see a doctor?

edit: i forgot to mention this is also associated with a few fairly large clots, usually about 2 or 3 golf ball sized clots during my period.
