I have probably had THE WORST experience with YAZ, than anyone else on this site. Please GOD do not go on this drug. It is pure poison, save yourself!!!! I am having horrible pain as I am writing this. OK, I have been on YAZ for about 9 or 10 months. My Doctor draws labs every year on all of her patients (just run of the mills things, to make sure you are still healthy.) By the way I am ONLY 21 years old. I was on Ortho Tricylen for about 3 years, but wanted to try something new. While on Orthotrycyclin, I had normal blood pressure, normal lab levels, painless periods and ovulation. This drug almost killed me, it might still. Within one year, I went from being a healthy 21 year old, to having my blood pressure increase every month until the doctor put me on a blood pressure med, which didn't help, so she increased that dose, which didn't help, so she added a water pill as well, which doesn't help. The highest my blood pressure went was 158/110. The doctor did a kidney ultrasound, everything was fine. I was having constant cramping on the left side of my pelvis for 3 months, the doctor did a uterus and ovary scan, and those were fine. the doctor ran blood work on me, My TRIGLYCERIDES (the fat in your blood) had TRIPLED in 9 months. That seems impossible to me, considering I had not gained any weight, in fact I had lost 10 pounds, and my cholesterol was not elevated, but was low. At the advice of the doctor I stopped taking the Yaz over a month ago. My period is almost 2 weeks late, and i am not pregnant. I am still having constant severe pain in my left ovary in my pelvic area. I had no sex drive on Yaz, and increased anxiety. I developed a strange fungal infection on my chin while taking Yaz. I do not have any diseases, and should NOT be developing a fungal infection on my FACE. I just hope my period comes back, I want to have a baby one day. I am very sad and hate myself for taking Yaz, please take this seriously.
