Many women don't experience a period until they are through breastfeeding (some for a year or more). Others will have an irregular cycle, or experience a period after reducing nursing to only 1-2 times per day. Women who feed their babies formula will usually begin menstruating anywhere from 1-3 months after delivery.

About the Lactational Amenorrhea Method (LAM)

Lactational Amenorrhea Method (LAM) is the technical way of saying you don't have a period while breastfeeding. Some women use this as a form of family planning. LAM is a temporary form of natural family planning that can be used by women who have recently given birth and are breastfeeding. To use LAM, you must be able to say yes to all four statements:

  • You ONLY breastfeed your baby. (You do not give your baby any other food, formula or drinks.)
  • You breastfeed your baby at least every four hours during the day, and every six hours at night – no exceptions.
  • Your baby is less than six months old.
  • You have not started your monthly period.

LAM is 98% effective for moms who can say yes to all four statements. If you can not say yes to all four, it's important to choose another method of birth control to prevent a pregnancy. Be aware that some kinds of birth control will reduce your breastmilk supply.

You have lots of options. Talk to your doctor to figure out which method is best for you.
