I've been on Yasmin for about 2 years or so, and before that, Ortho-TriCyclen for about 6 years. I've had no problem with Ortho-TriCyclen, but my Gynecologist switched me over to Yasmin due to my periods getting longer.
While I was on Yasmin, everything seemed fine, then a year later, I got a UTI. And I never get those! Nothing in my life had changed (same BF), and so I thought it was a one-time thing (or related to taking antibiotics at that time for a root canal). Well, I got UTIs 3 more times after that! Almost every month! However, during those months, I had switched to Ocella, so I thought it had something to do with taking the generic. Shortly after, I went back to Yasmin. I have had no UTIs since, but I also have been very careful to avoid it.
After the switch back to Yasmin (from generic), I noticed that I had NO sex drive and was dry, which was not like me. I also had melasma, which was noticeable to me and very annoying. I had recently stopped taking Yasmin altogether after searching for its side effects. It's been a month and a half now and my libido is coming back and the dark spots on my skin are beginning to diminish. Although my side effects were minimal compared to others here, I will not take Yasmin anymore. It's actually nice not to have to remember to take a pill everyday!
