birth control
"I have been taking Yaz for about 10 years, a few years ago I was given Loryna as a generic for Yaz and didn't think anything of it assuming it should be the same. While taking the generic I experienced extremely heavy periods that would last at least a week with a lot of blood clots. Typically my period is extremely light/no blood clots and lasts 3 days. I became very emotional and had drastic mood swings. Eventually my heavy period came and then didn't leave for an entire month, this made me realize the only thing that had changed was switching to generic Yaz. Once I switched back to yaz all these symptoms stopped. I ONLY get Yaz now."
