Mensural Cycle gone wrong.?

I recieved my period when i was 11. Up untill the age 13 & 14 that’s when i started to notice it was turing abnormal. I had a period for weeks and weeks (3wks or more) blood clots bad…. then. & they would also skip. When I turned 19 i started birthcontrol. It make them normal but then i quit taking them when i was just about turing 20 because i thought they were making me gain weight but it was my own genes doing that bit. I recently had surgery in Feb. 2009 because i was dignosed with an ovarian cyst and large mass tumor on my left ovary. Scarry but it was non-cancerous. I had open major surgery… the tumor was the size of 3L soda bottle. It was removed and I was recovering well… i was then again put back on birthcontrol for the next three months my periods were normal. perfect i loved it. After those three months…. i stopped the birthcontrol again because it cost 35 dollors a month for my daily pills and … my period has stopped as well.

what could this be? i’m not pregnate, i take pg test every two weeks, i dont drink, i smoke the ganja but that’s not harmful, i workout, i eat ok…, there is some stress in my life… i just dont’ know.
along with the removal of the tumor
they had to take my left ovary as well… so i only have one… my right.. could this make this big effect????
i haven’t had a period for 3-4months.

i found out last friday i had a cyst, i have had two weeks of pain and pg symptoms, turns out it was from the cyst. pain started sat night and went into early sunday morning. the pain was sharp side pains, and pinching pain in my ovaries. it got really bad and i was doubled over in pain crying and then it would settle down and get bad all over again. well then i got charley horse cramping in my abodmen and i was on the ground in tears and in fetal position i scared my roommate because i was crying and screaming kind of. so i went to the er,after a bunch of tests which showed nothing (they didnt do an ultra sound since i already had one which showed a cyst) she did a pelvic,i still had pain on the right side, when she pushed down it sent shooting charley horse pains up my side, it was determined that it had ruptured. im still getting sharp side pains,with some pinching pain. not nearly as bad, but still hurts, how long until it goes away? they said 2 days. never had this happen before.
when i went in the er there wasnt any bleeding, it said in my report (i work in the hosp and can get this) that i had calcifications in my pelvic area and had phleboliths which are like small blood clots, so i wonder if that is from the cyst. but the pain is still really bad. its all on the right side unless it is very heavy menstrual cramps. and its all that pinching pain and up the side of my right side and sometimes my back has the knife like stabbing pains up it too. er said they really couldnt do anything. the cyst ruptured here at my house, i didnt want to go sit in there for 8 hours espcially when i knew it was gonna rupture. this is day 4 after it happened early sunday morning. it was so intense yesterday at work i was in tears. i will make any apt with a gyne soon, but i cant handle another pelvic exam again right now. i guess maybe its because of the fluid or something in my body. i dont get the problems breathing at all. god i want my life to be normal again! thanks everyone
