Clots are dangerous as they travel to different parts of the body and relocate in places such as lungs. The birth control pills contain a drug named estrogen. The estrogen in the pill may activate the blood clotting for some women.

Chest pain is a symptom for blood clotting. Blood clotting is mostly faced by those women who smoke, are overweight, are sedentary, older than 50 years, have high blood pressure or are diabetic. Women who use estrogen containing pills are at an increased risk of developing blood clots. A blood clot can occur in the artery or vein having symptoms depending on the location of the clot. The clot can also form in the leg, abdomen heart or even lung.

A clot can also result into a stroke.  Birth control pills and smoking aren’t made for each other. The possibility of clotting is rare if the woman is healthy and in mid 30s and a non-smoker. When it comes to the risk of developing blood clots it is very much necessary to use the safest brands of birth control pills. Birth control pills with lower dose of estrogen can prevent blood clotting. However take guidance from doctor whether what pill will suit you.
