Lactation Amenorrhea Method (LAM)

What is the lactation amenorrhea method (LAM)?

  • LAM is a method of birth control. Lactation means your body is making breastmilk and amenorrhea means you aren’t having a monthly period.
  • LAM is a way for breastfeeding to temporarily  help prevent pregnancy. It must be used correctly to work.
  • Exclusive breastfeeding (this means not feeding your baby anything other than your breastmilk) helps prevent an egg from being released from the ovary each month. You can’t get pregnant if your body doesn’t release an egg.

How well does LAM work?

  • If no method of birth control is used, there’s about an 85% chance of getting pregnant after 1 year of having sex.
  • If used correctly (this means you follow the exact directions all the time) LAM provides protection from pregnancy, which is 98 percent effective for the first 6 months after giving birth.
  • LAM doesn’t protect you from sexually transmitted infections (STIs) and HIV.
  • Use a condom every time you have sex (vaginal, oral, anal) to lower your risk of STIs and HIV.

How do I start to use LAM?

LAM only works if your:

  • period has not returned (this means no spotting or bleeding for 2 months after you have had a baby) and
  • baby doesn’t go more than 4 hours between breastfeedings during the day or 6 hours at night and
  • baby is under 6 months old and
  • baby is fully-breastfed from birth (no other liquids/solids except vitamins, vaccines, or medicine) If you don’t have all 4 items listed above, you need to start another method of birth control.

LAM does not work if:

  • you have had a period (any bleeding or spotting in the 2 months after you have had a baby)
  • your baby goes longer than 4 hours during the day between breastfeedings or 6 hours at night between breastfeedings
  • your baby is more than 6 months old
  • your baby is no longer fully breastfed and you are giving pumped breastmilk, expressed breastmilk, or supplements like water, juice, baby formula, or baby food

What are the benefits of LAM?

  • LAM works for up to 6 months after birth, if you are exclusively breastfeeding.
  • It is effective right away.
  • There are no added hormones that can affect your breastmilk.
  • It is free and no birth control supplies are needed.
  • It is easy and doesn’t interrupt sex.

What are the disadvantages of LAM?

  • Sometimes a woman may find it hard to breastfeed her baby at specific times.
  • LAM is not an option for women who don’t breastfeed.
  • It can only be used for up to 6 months after you have your baby.
