Current research suggests that the progestin hormone in a specific type of birth control pill may increase a women's blood clot risk. However, it is unknown exactly how the progestin causes the increased risk. Researchers want to gather information to better understand why the progestin may increase a woman's blood clot risk. We hope this study can lead to developing a combined oral contraceptive pill with less risk factors for women.
