Breastfeeding and birth control pills: Can you use birth control pills when breastfeeding?

When the body is still finding its balance after childbirth, the question naturally arises:
Can one use birth control pills while breastfeeding – and does it affect the milk or the baby?

The short answer is: Yes, but it depends on the type – and there are several good alternatives.

Not all birth control pills are the same

There are two main types:

• Combined birth control pills (estrogen + progestin)
• Minipills (progestin only)

The difference is important when you are breastfeeding.

Which contraception is recommended during breastfeeding?

Generally, minipills are recommended during breastfeeding.

They do not contain estrogen and therefore do not affect milk production in the same way as combined birth control pills.

Combined birth control pills can in some cases reduce milk supply – especially if started early.

When can one start?

Minipills can typically be started a short time after childbirth.

Combined birth control pills are often only recommended when breastfeeding is stable and milk production is well established.

Advantages and disadvantages of birth control pills during breastfeeding

Minipills are often the first choice – but they have both advantages and disadvantages.

Advantages:

• do not affect milk production
• can be used early after childbirth
• high reliability when used correctly

Disadvantages:

• must be taken at the same time every day
• can cause irregular bleeding

Combined birth control pills can be a solution later – but require more consideration regarding breastfeeding.

Alternatives to birth control pills during breastfeeding

If you do not wish to use birth control pills, there are several good alternatives.

IUD (hormonal IUD or copper IUD)

An IUD is a very reliable form of contraception and does not affect breastfeeding.

Advantages:

• very high reliability
• does not require daily attention
• long-term solution

Disadvantages:

• requires insertion by a doctor
• can cause side effects depending on the type

Contraceptive implant

A small rod placed under the skin that releases hormones.

Advantages:

• very reliable
• effective for several years
• does not affect breastfeeding

Disadvantages:

• can cause irregular bleeding
• requires insertion and removal by a doctor

Condom

A hormone-free solution that many choose initially.

Advantages:

• no hormones
• can be used immediately
• also protects against infections

Disadvantages:

• lower reliability than hormonal contraception
• requires use at every sexual intercourse

Does contraception affect your baby?

For hormonal contraception, the amount of hormone transferred to breast milk is very low.

There is no evidence that it affects the child's development when contraception is used correctly.

When something feels wrong

If you experience changes in your milk production or your baby reacts differently, it is important to take it seriously.

Small adjustments in contraception can often make a big difference.

The most important thing: confidence in your choice

There is no single right solution.

Some need a reliable and long-term solution, while others prefer something more flexible.

The most important thing is that you choose contraception that:

• suits your body
• suits your everyday life
• feels safe
