The Pill Birth-Control Pills Most women take the combination pill, which contains two hormones, estrogen and progestin. The mini-pill, on the other hand, contains only progestin. Risks Of Combination Birth-Control Pills Women who are susceptible to blood clots might find some health risks in using combination birth-control pills. Who Should Use The Mini-Pill The mini-pill is ideal for women older than 40 who may not ovulate on a regular basis, and for women who are exclusively breast-feeding their infant.
