can you get pregnant while breastfeeding

Yes, you can get pregnant while breastfeeding, even if your period hasn’t come back yet.

Can you get pregnant while breastfeeding?

Breastfeeding often delays fertility for a while, but it is not reliable birth control. Your body might start ovulating again before you ever see a first postpartum period, which means you could conceive without warning.

Hormones like prolactin (released during breastfeeding) can suppress ovulation, especially when you are breastfeeding very frequently and exclusively. But as feeds stretch out, night feeds drop, or you add formula/solids, that hormonal “protection” weakens and your fertility tends to return.

How breastfeeding affects fertility

When you breastfeed often, your prolactin stays higher and can block the hormones that trigger ovulation. This is why many women don’t get a period for months postpartum if they are breastfeeding around the clock.

Common patterns doctors and lactation resources describe:

  • Many do not ovulate for at least 6 weeks after birth.
  • With exclusive frequent breastfeeding, ovulation may stay suppressed for up to about 6 months.
  • As soon as feeds are less frequent, longer stretches at night appear, or bottles/solids are introduced, ovulation can return at any time.

The key catch: ovulation happens before your first postpartum period, so you won’t get a “warning bleed” before you’re fertile again.

Lactational Amenorrhea Method (LAM): when breastfeeding acts like birth

control

There is a specific method called the Lactational Amenorrhea Method (LAM), where breastfeeding is used as a temporary, natural contraceptive. Under strict conditions, LAM can be quite effective in the first 6 months after birth.

Medical and reproductive health groups describe LAM as only likely to work if all of these are true:

  1. Your baby is less than 6 months old.
  1. You are exclusively breastfeeding (no formula, water, or regular solid feeds).
  1. You nurse at least every 4 hours in the day and every 6 hours at night.
  1. Your period has not returned at all (no true menstrual bleeding).
  1. No regular pumping or long gaps with pacifiers/expressed milk instead of direct feeds.

When these rules are met, some sources estimate pregnancy risk in the first 6 months at about 2% (similar to certain birth control methods), but it is still not 0%.

Once any condition is broken—baby older than 6 months, longer stretches between feeds, or period returns—LAM is no longer considered effective birth control.

Real-world chances of pregnancy while breastfeeding

Health organizations and clinicians consistently emphasize that breastfeeding reduces—but does not eliminate—your chance of conceiving.

General points they highlight:

  • Early months, exclusive breastfeeding
    • Lower chance of pregnancy, especially before 6 months postpartum and before return of periods.
* Still possible to ovulate and conceive, just less likely.
  • After about 6 months or with mixed feeding
    • Fertility usually starts to rise again as night feeds drop and solids/bottles appear.
* Risk gets closer to your normal baseline if you’re breastfeeding only part-time.
  • No period yet, but breastfeeding less
    • You can absolutely get pregnant in this situation because ovulation can happen silently.

Many forum stories online are from people surprised to learn they conceived while still breastfeeding and before their first period. They thought they were “safe” because of nursing, then found out they were pregnant months later.

If you do not want to get pregnant

Doctors and major health organizations generally advise not relying on breastfeeding alone as birth control. If another pregnancy now would be stressful, it’s important to use a proper contraceptive method.

Common postpartum options discussed in medical guidance:

  • Condoms (with or without spermicide).
  • Progestin-only pill (“mini pill”), often considered compatible with breastfeeding.
  • Hormonal IUD or copper IUD.
  • Progestin implant or injection (depending on your health and timing after birth).
  • Fertility awareness methods with extra caution, as cycles can be irregular while breastfeeding.

The best choice depends on your health, how recently you delivered, and whether you are fully breastfeeding, so it’s worth discussing with your own doctor or midwife.

If you do want to get pregnant while breastfeeding

If you’re hoping for another baby soon, breastfeeding may delay but usually doesn’t block fertility forever. Some people conceive while still exclusively breastfeeding; others find they only ovulate regularly after:

  • Reducing night feeds.
  • Spacing daytime feeds further apart.
  • Fully weaning or mostly weaning.

Because cycles can be irregular at first, you may find it harder to “track” ovulation. In that case, having regular unprotected intercourse a few times per week often covers your fertile window without precise tracking.

If you have been breastfeeding and trying to conceive for many months without success, your provider can help check whether ovulation has returned and whether anything else is going on.

Mini FAQ

1. Can you get pregnant while breastfeeding with no period?
Yes. Ovulation can happen before your first postpartum period, so pregnancy is possible even with no bleeding.

2. Is breastfeeding by itself good enough birth control?
Generally no—unless you meet strict LAM criteria and even then it is only considered temporary and not 100% reliable.

3. When is pregnancy most unlikely while breastfeeding?
In the first 6 months postpartum, with exclusive frequent breastfeeding, no pumping, and no period, the chance is relatively low but not zero.

4. When should I take a pregnancy test?
If you’ve had unprotected sex and notice pregnancy symptoms (nausea, breast tenderness different from normal, fatigue, or feeling “off”), or if your period was back and then disappears, it’s reasonable to test.
