I am 26, last December i was diagnosed with endometriosis. I was on yaz and doing pretty well for 7 months, no mood swings, normal sex drive, no weight gain. Then all of a sudden month 8 my period came 2 weeks late and didn't stop for 4 months! With in those 4 months i was given a ton of birth control to try and stop my bleeding. Yasmin was the last one. It took about a month but then my periods stopped and was normal after that. It has been a lot lighter. That has been the only good part. I still get severe menstrual cramps and every month i get more and more depressed. I have no desire to be with friends go to work or anything i love. I get the worst mood swings, sometimes i feel like i am going to walk away from my marriage, my great marriage! Literally i tur so dark and loose desire to work, clean , work-out...anything. Im very concerned this is because of this pill.
