"i started loryna about 3 and a half weeks ago. i was preparing for an ivf embryo transfer. i wanted to select yaz as the birth control to prepare for my transfer, but learned yaz is no longer on the market. this should have been my first clue that a generic form of a drug that was off the market might still not be safe. i started taking lornya. about a week and a half of taking it, i felt a pain in my calf. the pain intensified to the point i could hardly walk. i decided to check on this and it was found that i formed a blood clot behind my knee. i was advised to stop loryna immediately. i now have to take 2 shots a day of blood thinners for 3 to 6 months. i also think my ivf will be cancelled because of this. no history of blood clots."
