Drospirenone / ethinyl estradiol
menstrual disorders
"I've been on Yaz for three months.  I started taking it because I told my doctor that I had really bad moodiness during PMS.  Ha, it's gotten worse!  I don't start my period till the last day of inactive pills.  My cramps feel like I'm 15 again (I'm 36) and my mood swings have worsened.  Barely any sex drive.  I'm going back to Ortho-Tricyclen (Trinessa)."
