I am so glad I found this website! Since starting YAZ 2 months ago because I was diagnosed with PCOS and had not had a period for about 3 months I have not stopped bleeding! Heavy bleeding not just spotting. I have had severe cramping as well. I cry at things that normally wouldn't bother me. I get angry at my husband for little things that aren't even worth being upset about. I am almost always nauseated a few hours after taking YAZ and I barely have a sex drive! This is not me at all. My ovaries actually hurt when I walk or even sit, I can just feel them throbbing. Not only that I am very tired all the time no matter how much sleep I get. Thank you all of you for posting your reactions to this birth control on here.
