millions of women take BC pills and never develop blood clots or have any issues at all with the product. However, here at az, many anxious women worry about all kinds of things, particularly with regard to medications. Personally I don't think you are twitching or cramping because of dehydration or low potassium or blood clots. I think you are having these twitches and muscle spasms etc due to your fear of blood clots/taking medication or just anxiety in general. the mind is a powerful thing. it can produce just about any body ache/pain that fits the disease/illness that you fear. You have seen two doctors and both are not concerned. You say that you realize they aren't but you still are. May I ask: if you aren't going to find any solace, at all, in the professional opinions of two doctors, why did you go and see them?
