As I breasfeeding it is safe to my baby and to my health to take lady pills?

Do you man ith control pills? If so, it's safe, but they tend to decrease the amount of breast milk you produce.

As J_9 said, you may see a decrease in milk production, especially with a combination pill. If you use the mini-pill, which is progestin only, it is usually less of an issue... this may be even less of a concern if milk production is well established and baby is at least several weeks old. You'd have to try it and see how it goes for you. You may or may not notice too much change. Safety wise, either is fine as was said.
