At any given time, approximately 62% of all women of reproductive age are using some form of a contraceptive for the prevention of an unintended pregnancy.  Out of those women regularly using a contraceptive, around 53% of unplanned pregnancies will still occur.  There are many forms of contraceptives women can chose from more than what was available in the past – birth control pills, other hormonal methods of the patch, implant, injectable and vaginal ring, IUDs and condoms. With so many different options available, why do women who are using contraceptives, still become pregnant?
