Irregular period cycle symptoms and conditions

I am so happy to have found this site.... I have been on Yasmin for a little over a year. I had read side effects prior to taking it but had to be put on it due to the fact that all my life I have had an irregular period cycle. I figured that everyone was different so I started taking it. I did fine up until a few months ago. I started experiencing nausea and terrible chest & abdominal pain. They found out I had a bacterial infection so related it to that. But after that was cleared up I still had the problems... went to the ER who ran tons of tests... catscan, EKG, x-rays, blood work.. the whole thing, and everything came back 'normal'. Then I started experiencing anxiety and panic attacks... seemed like they always were in the evening making it very hard for me to fall asleep. I felt nervous all the time. Then I found this site and so many here have experienced everything I have. I immediately stopped taking yasmin and went into see my obgyn. Right now I am not taking anything until I get back to feeling like me again... I hear it takes a while for the pill to completely leave your system, does anyone know how long? I am starting to feel a little better, but still experiencing the same problems... just not as strong. The heart palps and chest pain, which makes me feel like I can't breath, scare me the most...
