LACTATIONAL AMENORRHEA METHOD
For women who have recently had a baby and are breastfeeding, the Lactational Amenorrhea Method (LAM) can be used as birth control when three conditions are met:
1) amenorrhea (not having any menstrual periods after delivering a baby)
2) fully or nearly fully breastfeeding
3) less than 6 months after delivering a baby. LAM is a temporary method of birth control, and another birth control method must be used when any of the three conditions are not met.
