I'm 17 and every month is the same thing, one week before my period I gain 6 pounds, I can't fall asleep and when I do I can't wake up, I have absolutely horrible moodswings that alter my relationships with people, and when I say it's PMS people say it's not an excuse.
More over the past year than ever I have gotten severe cramps in my back and lower stomach and it seems like rectum that end up in nausea (but never vomitting) and diarhea. This is only during PMS mode. I was recently at an assembly where I had to sit for a lot of hours, and the sickness would just come in waves of unbearable pain, about 6 waves of the pain per hour.
When PMS and my period are gone, I feel great and I'm back to my regular, happy self.
My mother will not allow me to go on contraceptives, so, if that is a cure for anything I have, if there are any other alternatives I would appreciate it.
Could these be symptoms of endometriosis? PMDD? Anything other medical condition??
Thank you in advance.
My period is anywhere from 33-44 days (never 28) and lasts about 5 days, regular bleeding, not like soaking through a super maxi pad and tampon like my friend does, but, thats basically all the symptoms I've got.

its just bloating is all.its not endometriosis bc that dont come n go. take some midoll to help out although the waves of unbearable pain could b something wrong with ur uterus not contracting like it should. the muscle that is. I have one step worse then endometriosis n fibroids n adhesions n goin thru PT for my uterus. get checkd out. if they say its nothing get a second opinion. get a colonostipy too.
