Women who are breastfeeding have special needs when selecting a family planning method. Family planning counsellors should be sure to inquire whether the client is breastfeeding and offer complete information about each method including any possible effects it may have on the quality and quantity of her breastmilk.

Methods can be classified into three categories based on their effect on breastfeeding.

1st Choice Methods

These methods do not interfere with breastfeeding and are safe to use any time after birth:
LAM (for up to six months)
Condoms (also the best protection against AIDS and sexually transmitted diseases)
Diaphragm
Spermicides
IUD (non-hormonal)
Natural Family Planning (breastfeeding disrupts the signs and symptoms of fertility, which may make charting difficult)
Vasectomy
Tubal Ligation

2nd Choice Methods

Methods under this category contain the hormone progestin. In most cases, these methods do not affect a woman's milk supply. However, to avoid any risk, it is recommended to wait six weeks after delivery before using a progestin-only method, which include the following:
Mini-pill
Injectables
Implants

3rd Choice Methods

These methods contain the hormone estrogen, which can reduce a woman's milk supply. Women should be informed of this risk and advised to delay the use of such methods until at least six months postpartum. However, if the breastfeeding woman chooses this method, she can continue breastfeeding and should be encouraged to do so for its numerous health benefits.
Combined oral contraceptives
Combined Injectables
