birth control
"I was taking Yaz for almost 7 years and I loved it! My weight never changed, my skin was beautiful, normal sex drive, no cramps, 3-4 days periods. In 2013 I saw some weird spots on my face, after the consultation with a doc it turned out to be Melasma (nothing dangerous but it doesn't look good) . One of the most common causes is oral birth control. It wasn't the Yaz, just birth control with higher amount of progestin. I switched to Mirena and that was the worst decision ever! Acne, mood changes, gained 20 pounds in 3 weeks. I'm going back on the pill this month and we will see how it goes, I will post about it in about 6 months."
