I've been using Yaz for a few months now, four to be exact and ever since I experience severe nausea in the afternoons & evenings, very rarely in the morning.The only time I don't feel nauseous is when I'm using the inactive pills. I feel tired and drowsy throughout the day & recently I've been getting hectic cramping in my chest, oh and my heart rate seems to have picked up a lot. It never beats slowly anymore even if I'm just sitting down and relaxing. I'm pretty stressed out about this, anyone else had some/all of these symptoms?
