it's been 20days and i m not getting my periods.. m doing breast feeding... is it normal?

A. Typically, women who are breastfeeding don't get their periods as quickly because of the body's hormones. Prolactin, the hormone needed to produce breast milk, can suppress reproductive hormones. As a result, you don't ovulate or release an egg for fertilization. Without this process, you most likely won't menstruate.
