Can You Use Breastfeeding for Birth Control? An Ob/Gyn Explains
It sounds too good to be true, but here’s how it actually works.

Breastfeeding could keep you from getting pregnant? This one sure sounds like a hoax, but breastfeeding can help prevent pregnancy under very specific circumstances. It’s a form of birth control known as the lactational amenorrhea method (LAM).
But—and this is important —you do have to follow specific guidelines to ensure you do not accidentally get pregnant while breastfeeding, according to og/gyn Kecia Gaither, MD.
How Breastfeeding May Work as Birth Control
If you nurse your baby at least every four hours (or six during the night), and you feeding your baby only breast milk, your body will naturally stop ovulating. No ovulation means no eggs to fertilize, so you can’t get pregnant. (It also means no period, which is what the “amenorrhea” refers to.) For more details, here’s an overview of how ovulation and menstruation really work.
The LAM method only works for the first six months after your baby’s birth, and it won’t work if:
-
You feed your baby formula or anything other than breast milk (even if you’re using a combo of each).
-
You use a breast pump.
-
You feed your baby solid foods.
When to Switch to Another Method
If your baby is over six months old, or you are feeding your baby anything other than breast milk, use another form of birth control to prevent pregnancy. Immediately after birth, you should use an estrogen-free method, like the shot, implant, Skyla and Mirena IUDs, or progestin-only pills. Don’t use birth control methods with estrogen, like the Pill, patch, or ring for the first three weeks after delivery.
When used effectively, breastfeeding with the LAM method is about 98 percent effective at preventing pregnancy.

Can I use breast feeding as birth control?
00:04.900 --> 00:10.153

00:10.153 --> 00:13.690
My new mommy patients have
lots of questions about that.
00:13.690 --> 00:18.272
The answer is yes, but,
you have to follow a number of specific
00:18.272 --> 00:22.436
steps in order to not get
pregnant while breast feeding.
00:22.436 --> 00:26.292
When you breastfeed exclusively,
every four hours during the day and
00:26.292 --> 00:31.300
every six hours at night, your body stops
ovulating, so you can't get pregnant.
00:31.300 --> 00:34.480
But, if you combine breast milk and
formula or
00:34.480 --> 00:39.150
pump, breastfeeding as birth
control won't be as effective.
00:39.150 --> 00:42.510
Use another form of birth control
when your baby is six months,
00:42.510 --> 00:47.060
you get your period back, or if you
start feeding your baby formula or food.
00:47.060 --> 00:49.060
If you wanna be safe while you're nursing,
00:49.060 --> 00:53.370
even use other forms of birth control that
won't have any impact on your milk supply.
00:53.370 --> 00:56.810
You can start using the shot,
implant, IUDs, and
00:56.810 --> 01:01.410
some types of birth control pills called
mini pills right after giving birth.
01:01.410 --> 01:06.200
You shouldn't use a method that has the
hormone estrogen, like the pill, patch or
01:06.200 --> 01:09.290
ring, for
the first three weeks after giving birth.
01:09.290 --> 01:11.531
After three weeks,
you can start any of these methods.
01:11.531 --> 01:14.211
