I am a mother to an 11month old boy and still breastfeeding. Well I would like to know if the pill Plan B one step is safe while breastfeding help?

Please see: . http://ec.princeton.edu/questions/ecfeeding.html.. "using progestin-only emergency contraceptive pills once will probably not affect either the quantity or quality of the milk your breasts are producing. Although some hormones may be passed on through a mother’s breast milk, your child is not likely to experience any adverse effects from it." however, Ella (ulipristal acetate) label recommends against it.
Yes. It may cause a decrease in milk supply and some nausea for you but should not affect the baby otherwise.
