Free period symptoms and conditions

I have been very ill for almost three months now. I kept feeling like I was going to pass out at work - the same time everyday. Chest pain - under my left boob (around my heart area). Went to doctor's just before Xmas, he took my blood pressure and rushed me up to the hospital. Had ECG, Chest X-ray, Blood tests, but all of them came back okay?! Have since has an ultrasound, and am booked in for a 48 hour heart monitor in a few weeks. Off my own back, I stopped taking the pill when they couldn't find anything wrong, and I read the side effects, and this was on the 26th december. The feeling faint has almost totally gone (apart from when I start to panic about feeling faint), but I still have this 'stitch/hunger pain' feeling around my heart area everyday. You feel like it's gone, and then the pain happens. I am scared that it's something serious ( have little faith in doctors anyway). I have had two periods since coming off of it, and yes, they may be heavier, but rather that then feeling like you are going to die. I am not exaggerating. At one point over xmas, I told my boyfriend to call an ambulance because of the hot, numbness in my legs. The second yasmin free period I had, was a week or so ago, and I did feel a bit faint during. When I last saw my doctor, I explained what I had done, and he wouldn't commit himself, he just said that it could be Yasmin. I'm getting married in November, but until I know that I haven't got something seriously wrong, it's hard getting excited. If I have permanent damage from this pill, surely I can sue?
