Dr. Cherise Wiley did something lots of women do. She switched birth control pills to save money, opting for a cheaper alternative. Estrogen increases the risk for blood clotting and within a month Wiley's decision had turned the doctor into a patient.
She had chest pain and shortness of breath. Wiley has a disorder that makes her more prone to blood clots which she didn't know about before it pushed her risk factors over the line. Blood clots are just one the risks associated with contraceptives.
Dr. Haddock says studies are constantly underway examining the risks of various contraceptives, "they all have different pluses and minuses and every person is different which one is going to work for them."
