birth control
"I am 21 years old, non-smoker, do not drink often, exercise regularly (aka. poster child of health, I was a college athlete as well...I don't even have a cavity!) I recently got diagnosed with DVT (blood clot in leg) and a pulmonary embolism.  I was on Junel FE and the 3 doctors I saw said it was due to the birth control.  DO NOT TAKE THIS!  I know it is considered a "rare" side effect, but it can happen to you easily.  Apparently it is not as rare as I thought.  The medication is VERY costly and you may have to be on blood thinners for the rest of your life. Be careful."
