I started taking Yasmin about 3 months ago. About a week ago, I fainted and had to go the ER. There they found that my heart rate was irregular so they put me on a heart monitor. A day later I was back in the ER because of chest pains and a shortness of breath. Two days after that, I was in the ER once again due to my extremely high heart rate and pain in my legs. They told me it was my thyroid levels that were causing this, so I found a different doctor who said it was not my thyroid but had no idea what it was. I ended up going to a cardiologist who just told me I was under a lot of stress. I asked each doctor if my birth control could have anything to do with it, and they all told me no. Well, after finding this website, I can now see that it is Yasmin causing my health problems. Thank you all so much for posting your stories...they really saved me!
