Well I don't take Yasmin, but I do take Yaz. I have been taking Yaz for about three years now --- I'm 25 and have been on the pill since 15 yrs old. I take the pill b/c I have ovarian cysts and have found that it does help, but doesn't make them go away or relieve the pain. In regards to Yaz, I haven't received my period for the last 10 months, which to me isn't normal. My OBGYN said that a lot of people who take Yaz have been experiencing the same side effects, but to me it just doesn't seem normal to not have a period, especially when I'm on a birth control that is supposed to help regulate my period. I have an appt w/ my OBGYN in early Oct and definitely going to bring up this website with her. Thanks for all the information that's posted here - it is truly helpful.
