Yasmin has been hell for me. When I first took Yasmin, breakthrough bleeding has occured for 2 months (i expected this, and it is somewhat common). I always had migrane headaches without taking BC, but while on Yasmin i haven't experienced any less, or any less painful migrane headaches. About 4 months in, i start to feel pressure on my esophagus; at the time, I didn't think much of it. About halfway through the 4th month, I realize my eating habits have changed drastically. I feel full all the time, and unwilling to eat any food because of the pain and pressure i felt on my esophagus. Then it hit me, completely while i was on vacation. I was vomiting non-stop due to acid reflux, because nothing could go into my system, even water. Acid reflux has continued to effect my life while on Yasmin. I've gotten an Upper G.I done to only find irritation on my esophagus, which i believe is surely from taking Yasmin, because i've never had any other digestive problems before taking a BC pill. Now, i'm on Ortho-Tri cyclen lo, I've only been taking it for about 3 days though. At the moment I'm experiencing EXTREME migrane headaches, and this is what I assume is from withdraw, hopefully it will be gone for good when my body gets used to Ortho-lo.
