Breastfeeding Can Be Used as Birth Control IF …
Myths abound that you can’t get pregnant while breastfeeding. It’s true that you can get pregnant while nursing, but you can also use breastfeeding as a reliable form of birth control – in some cases – until your menstrual periods return on a normal cycle.
Does that sound confusing?
- Yes, breastfeeding works as birth control. For certain women under certain conditions, it is 98 to 99.5 % effective, which is as effective as the pill or condoms for pregnancy prevention.
- If your regular periods have returned, you can get pregnant while breastfeeding.
Breastfeeding Can Be Used as Birth Control If:
- Your baby is exclusively breastfed, night and day
- Your baby is under 6 months old
- Your periods have not returned
You can increase the effectiveness of nursing as birth control by breastfeeding on cue, breastfeeding for comfort, and not using bottles or pacifiers at all. These factors all increase the amount of time baby spends at breast.
While rare, you can get pregnant before your periods return, especially if your nursing baby is:
- Eating solid foods and drinking formula or cow’s milk as well as your milk
Getting Pregnant Without Having a Period
In some rare cases, an egg will be released as your cycle returns, but will immediately be fertilized. This is how some women can go two years or longer without a menstrual period. Babies born within 12 months of each other are often the result of this situation.
For mothers who breastfeed, however, they will usually have at least 6 months of protection against pregnancy – again, providing the baby is exclusively breastfed on cue and is not yet sleeping through the night.
What If You Get Pregnant While Still Nursing?
Once your periods return, nursing is no longer an effective means of birth control. However, the good news is that it’s very rare for a woman to conceive before her period returns. The first few periods in a new cycle after childbirth tend to be anovulatory, a period where no egg is released.
Don’t worry – there’s no need to immediately wean your baby, whatever his age. Many women successfully nurse through their pregnancy and then “tandem nurse” (nurse both an infant and a toddler) after the new baby is born.
Around the second trimester, your milk may change in taste and composition as colostrum begins to come in to feed the baby on the way. At this point, many toddlers will self-wean. Others will turn to nursing only to fall asleep or for comfort, increasing their intake of solid foods and decreasing their time at the breast.
Mothers who tandem nurse say their children are closer, learn how to share better, and experience less sibling rivalry and jealousy.

don’t think it’s right to encourage it without also informing that it had the potential to cause a miscariage.
THIS IS A MYTH- While nursing can cause uterine contractions, and sometimes initiate a full term pregnant woman to go into labor, there is no evidence to support that nursing has ever caused a miscarriage. In fact short of major trauma or drug use, there is not much you can do to actually cause a miscarriage. The vast majority of miscarriages are caused by genetic abnormalities.
A pregnant woman should be aware though, that the hormones associated with pregnancy may cause your milk to lessen or dry up.

I was a new mom and breastfeed my son till he was 7 months. My periods returned to normal after 3 months and i had regular sex with my husband after my periods returned but i did not conceive till now. We dont use any birth control, even then i get my periods normally.

I became pregnant when I was still nursing my 4.5 month old daughter, who I became pregnant with after 3 months on the pill (I realize I may be the exception to common rules).
While I like the idea nursing for as long as possible, I don’t think it’s right to encourage it without also informing that it had the potential to cause a miscariage. When you nurse, it causes you uterus to contract, posing a danger to any pregnancy that may have occured.
I belive every mom has a right to do whatever they think is best for their children, but I also belive that they should be given all of the facts.

I am now tandem nursing my 1 week old and 20 month old sons. My period returned after 10 months of breastfeeding and I was able to get preggo (on purpose) just one month later. I did find that breastfeeding and paying attention to my cycle (once it returned) was enough birth control for us…but we knew we wanted another child soon anyway, so a mistake would not have been devastating. 🙂
