Exercise patterns symptoms and conditions

I am 21 and have been on YAZ for 6 months, I am soo happy I came across this website. I only went on it (my first BC pill) because my periods are like 8 days long and on the first day I become so sick I can most often barley even function w/o the help of pain killers (in addition to pregnancy prevention). I am about to throw this last pack out I cannot take it anymore. My boobs were naturally a large B small C ...they have exploded into a large D..it does not fit on my frame...no clothes fix me and my stomach is never flat always bloated!!!
I did not change any of my diet or exercise patterns. My boobs are so painful alll the time, I sleep w/ a bra on sometimes. I was always a moody person but recently I have been having crying spells for no reason or overreacting and at times embarassing myself. I was about to call a shrink to go on anti-derpressants! My boyfriend has been verbally attacked for the msot ridiculous things. I do not feel like myself. I called my doc and he said this one should not me doing this to me. My periods last for 6 days and sometimes I still have debilitationg craps. I have also been suffering from IBS!
He gave me a sample of LOESTRIN24? I read the side effects and they sound just as bad!! At this point I'm willing to deal w/ the cramps and use another form of pregnancy prevention! Does anyone have any advice? I want the cramps to go away and I want no weight gain unless it is from eating too much!! not the hormones! Thanks and good luck to everyone

I've been on Yaz since November 2006. So, for 9 months. My mood swings are MUCH better, however I have NOT changed my eating or exercise patterns and have in the last month and a half gained 6 lbs. I also have noticed - beginning in July, darkness above my upper lip (this is driving me crazy)
