Take control of your fertility cycle!
Birth Control for iPhone is an additional way to provide you with anti-conception. It is a natural way to prevent unwanted pregnancy based on the Calendar method.
Simply input the first day of your last menstruation and the usual length of your cycle. This app will output your predicted ovulation date. Your fertile days, if you are not using artificial contraception methods, take place between the 5th day before and the 5th day after ovulation date.
