i've been on Yaz for 4 months. My doctor switched me, trying to correct what he thought was vaginal dryness caused by ortho tri cyclen lo. It wasn't at all. I've had the same sexual problems. But, I've had a horrible time with Yaz. My period has been all messed up. My period usually comes one day, and is horribly heavy for one day. I mean, like gushing heavy. Then it turns brown for the next 5 days, sometimes longer. Also, my moods have been weird. I have random mood swings now. Where I want to cry at one point for no reason, then I go back to normal. But, today was the last straw. On my way to work, I felt a random crying spell come over me. Then it turned into depressed that made me want to kill myself. So, I'm assuming the mood altering parts in the pill are similar to anti depressants, and made me feel suicidal.
