I'm breast feeding which contraceptive pills can i take?

Progesterone only,: no estrogen. Combination estrogen/progesterone pills, may decrease milk volume, in some cases.

Mini-pills: Progesterone-only pills (mini-pills) are preferred as they are less likely to decrease milk supply, compared to combination pills. However, some women are sensitive to even progesterone-only medications, so it is better for women to use progesterone pills before considering progesterone injections such as DepoProvera. This injection lasts 3 months and can't be reversed after being injected.
