Lactational Amenorrhea Method (LAM)

Early Postpartum – Breastfeeding Women

  • Likelihood of menses and ovulation is low
  • Ovulation may occur prior to menses
  • Luteal phase is frequently defective

Less than 2% have an adequate luteal phase
that results in pregnancy

Slide 10

Health providers may express concern that an intensively breastfeeding woman can get pregnant before the return of first menses. However, there are a number of reasons why pregnancy is not likely, especially during the early postpartum period.

Researchers have discovered that the likelihood of the early return of ovulation and/or menses is very low in postpartum women who breastfeed intensively. However, some women who do breastfeed intensively may have their menses return and/or ovulate during the first months postpartum. And, in some of these cases, ovulation may precede menses.

However, research has also shown that the luteal phase of these initial cycles is often defective. A defective luteal phase is characterized by progesterone production that is not sufficient to prepare the uterus and sustain a pregnancy. Studies show that less than two percent of women who breastfeed intensively during the first several months postpartum experience an adequate luteal phase that results in pregnancy.
