Breastfeeding and Birth Control: What Methods Are Safe
Progestin-only methods — the mini pill, hormonal IUD, implant, or progestin-only injectable — are generally preferred while breastfeeding. Combined estrogen-progestin pills and patches may reduce milk supply, especially before supply is fully established, and are typically deferred until at least 4–6 weeks postpartum.
Why does the type of birth control matter when breastfeeding?
Estrogen is the main concern. High-dose estrogen has been associated with reduced milk supply, particularly in the early weeks after delivery when milk production is still being established 1Ref 1American College of Obstetricians and Gynecologists (2019).ACOG Practice Bulletin No. 206: Use of Hormonal Contraception in Women With Coexisting Medical Conditions.ACOG guidance on hormonal contraception during lactation: estrogen-related supply risk, timing for combined methods, and progestin-only safety during breastfeeding. Progestin alone does not appear to have the same effect on lactation.
The postpartum period is also a time when unintended pregnancy can occur sooner than many people expect — ovulation can return before the first menstrual period. Contraceptive counseling at the postpartum visit is an opportunity to choose a method that protects your milk supply while meeting your family planning goals.
Which birth control methods are safe while breastfeeding?
Non-hormonal options (no effect on milk supply) [1, 2]: - Condoms, female condoms, diaphragm, cervical cap - Copper IUD (Paragard): highly effective, lasts up to 10 years, can be placed at the postpartum visit or after 4–6 weeks - Lactational Amenorrhea Method (LAM): exclusive breastfeeding on demand, before any menstrual period returns, and within the first 6 months postpartum provides meaningful contraceptive protection — but all three conditions must be met exactly
Progestin-only hormonal options (generally compatible with breastfeeding) [1]: - Progestin-only pill (mini pill, e.g., norethindrone or progestin-only desogestrel preparations) - Hormonal IUD (levonorgestrel-releasing: Mirena, Kyleena, Liletta) - Hormonal implant (etonogestrel, Nexplanon) - Progestin-only injectable (medroxyprogesterone acetate, Depo-Provera): typically started after 6 weeks postpartum
What about combined estrogen-progestin methods?
Combined oral contraceptive pills, the patch (Xulane), and the vaginal ring (NuvaRing) all contain estrogen. Estrogen-containing methods are generally avoided or deferred in the early postpartum period because of their potential to reduce milk supply 1Ref 1American College of Obstetricians and Gynecologists (2019).ACOG Practice Bulletin No. 206: Use of Hormonal Contraception in Women With Coexisting Medical Conditions.ACOG guidance on hormonal contraception during lactation: estrogen-related supply risk, timing for combined methods, and progestin-only safety during breastfeeding. ACOG guidelines suggest waiting at least 4–6 weeks before starting an estrogen-containing method in breastfeeding patients, and some experts recommend waiting until breastfeeding is well established — at least 6 weeks 1Ref 1American College of Obstetricians and Gynecologists (2019).ACOG Practice Bulletin No. 206: Use of Hormonal Contraception in Women With Coexisting Medical Conditions.ACOG guidance on hormonal contraception during lactation: estrogen-related supply risk, timing for combined methods, and progestin-only safety during breastfeeding.
If your milk supply is established and stable, the risk may be lower, but the preference for progestin-only methods during the breastfeeding period remains.
Does birth control affect breast milk quality for the baby?
Small amounts of hormones from progestin-only contraceptives do pass into breast milk, but they have not been shown to cause harm to breastfed infants in available studies [1, 2]. The AAP and ACOG both consider progestin-only methods compatible with breastfeeding.
Combined estrogen-progestin methods carry more theoretical concern for both supply reduction and infant exposure, which is why they are deferred early postpartum.
When should I talk to my provider about birth control after birth?
Ideally, discuss postpartum contraception before delivery or at your first postpartum visit. Long-acting reversible contraception (LARC) — the IUD or implant — can often be placed immediately after delivery or within the first few weeks, before the 6-week visit 1Ref 1American College of Obstetricians and Gynecologists (2019).ACOG Practice Bulletin No. 206: Use of Hormonal Contraception in Women With Coexisting Medical Conditions.ACOG guidance on hormonal contraception during lactation: estrogen-related supply risk, timing for combined methods, and progestin-only safety during breastfeeding.
If you are concerned about your milk supply and are using a hormonal method, a lactation consultant can help you evaluate whether the method may be a contributing factor. Gale's care team can help coordinate a postpartum visit and contraceptive counseling.
Common questions
Can I start the mini pill right after giving birth?
Progestin-only pills are generally considered safe to start immediately postpartum or within the first few days. Discuss the specific timing with your obstetric provider — most recommend starting within the first week.
Will the hormonal IUD affect my milk supply?
The hormonal IUD releases a very small local dose of levonorgestrel (a progestin), and available evidence does not show a negative effect on milk supply. It is considered one of the most compatible hormonal options with breastfeeding.
Can I use the Nexplanon implant while breastfeeding?
The Nexplanon implant contains etonogestrel (a progestin) and is generally considered compatible with breastfeeding. It is one of the most effective reversible methods and can be placed immediately postpartum or at a follow-up visit.
Is it possible to get pregnant while breastfeeding?
Yes. Exclusive, on-demand breastfeeding suppresses ovulation but is not a reliable form of contraception unless all LAM conditions are met: fully exclusive breastfeeding, no return of your menstrual period, and within the first 6 months postpartum. Outside these strict conditions, a dedicated contraceptive method is recommended.
Breastfeeding and birth control: things to discuss with your clinician
- —Notable decrease in milk supply after starting a hormonal method — contact your provider
- —No return of periods by 6 months while breastfeeding — a provider visit is appropriate
- —Signs of IUD expulsion (can feel strings change or feel the device) — see a provider
This article provides general information about contraception options during breastfeeding. Individual decisions about birth control depend on your health history, milk supply, and family planning goals. Gale's clinicians can discuss these options with you at your postpartum visit.
