Your breasts go through changes when you have your period, when you become pregnant or breastfeed, when you go through puberty or when you go through menopause. But beyond these stages, how do we know what is normal and what is not?

There are four to eight different types of nipples. Your nipples may be flat, inverted, protruding, or indifferent. However, it is completely normal for nipples to be inverted rather than protruding.
