How would i know if i successfully completed pubertal development? is that simply having had an occasional period and pubic hair?

Several year sequenc: Puberty takes place over a period of several years in which a number of the parts of your body change both internally and externally and you become capable of having children. There are many good books and websites on the stages of puberty. There is no sharply defined border for that and girls frequently mature before boys and attract the attention of boys early.
