Breastfeeding mothers who do not experience a normal menstrual period are considered to have lactation amenorrhea. The condition is considered a natural means of birth control. When used as a method of birth control, lactation amenorrhea is called LAM (lactation amenorrhea method).
Not all women experience significant lactation amenorrhea. Some women begin ovulating again within a few months of birth and their regular menstrual period returns. Other women don’t ovulate or have a period for more than one year.
