hi i am 19 years old and have been on Yasmin for almost 2 years. at first it was great decreased my pms symptoms. Just recently my period flow has picked up I get cramps again and have had a yeast infection back to back with a UTI and now i think a bacterial infection. I also have noticed a dramastic change in mood swings. I will cry for no reason, feel unhappy for no reason, and just be angry for no reason. I am an emotional person, but I usually can control myself. I find myself getting mad at my boyfriend and friends for no reason, and i cant control the mood swings. has this happend to anyone? and why has it taken so long? I was just wondering if anyone has had the same problems. thanks!
