Birth Control & Breastfeeding: What You Need to Know

So, you just had a baby, and while you’re deep in the world of feeding, diapers, and Googling weird baby noises, you also need to think about birth control. But what about your milk supply? Can birth control mess with it? The short answer: it depends on the type!

Hormonal Birth Control & Milk Supply

Some forms of birth control contain estrogen, which can reduce milk supply—sometimes dramatically. Other options are considered safe and have little to no impact on breastfeeding. Here’s the breakdown:

❌ Birth Control That Can Lower Milk Supply

These contain estrogen + progestin:

• Combination birth control pills (Yaz, Ortho Tri-Cyclen, etc.)

• The patch (Xulane, Twirla)

• The vaginal ring (NuvaRing, Annovera)

Estrogen can interfere with prolactin, the hormone that keeps your milk flowing. Some people notice a drop in supply within days of starting, while others have no issues. If you really want a combo method, waiting until 6+ months postpartum (when supply is well-established) may reduce the risk.

✅ Breastfeeding-Friendly Birth Control Options

These are progestin-only or non-hormonal, meaning they won’t mess with your milk:

• Progestin-only “mini-pill” (e.g., Norethindrone)

• Hormonal IUDs (Mirena, Kyleena, Skyla, Liletta) – some people report a slight dip in supply, but most do just fine

• The implant (Nexplanon) – generally milk-safe but can absolutely decrease milk

• The shot (Depo-Provera) – can be iffy; some report a supply drop and if it does you can’t take this choice back

• Copper IUD (Paragard) – completely hormone-free, no supply impact

• Barrier methods (condoms, diaphragms, etc.) – zero effect on milk

What’s the Best Option?

If you want zero risk to supply, go for:

✔️ Copper IUD

✔️ Barrier methods

If you want hormonal birth control with low risk, try:

✔️ Progestin-only mini-pill

✔️ Hormonal IUD

If you’re okay with a potential supply drop, you might tolerate:

⚠️ Combination pills (estrogen + progestin), but best to wait until 6+ months postpartum

⚠️ The patch or ring (same estrogen concern as combo pills)

⚠️ Depo-Provera (some do fine, others lose supply—tricky one!)

The Bottom Line

✅ Estrogen-based birth control = higher risk of lowering milk supply

✅ Progestin-only or non-hormonal methods = safest for milk supply

✅ If you notice a drop in supply after starting a new method, talk to your provider ASAP!
