The pill containing estrogen and progesterone is generally safe for young, healthy non-smoking women. However, it can increase the risk of heart problems when other risk factors for cardiovascular disease are present. These can include being over 35, having high blood pressure or diabetes, smoking, experiencing migraines with aura, or having a history of stroke, heart attack, or blood clots. If you have been taking the pill for a long time and have recently experienced palpitations, there could potentially be a connection, but there are other possible causes to consider. It's important to consult with your cardiologist before making any decisions about stopping the pill.
