When will my first period come?

You ever hear the saying, "Everybody develops differently"? Nobody can predict when they will undergo puberty or have their first menstrual period, so just relax. However, brown residue found after a discharge is deoxygenated blood that has stayed in the uterus for too long. This occurs in every woman's first period, so you're close to having one. This is similar to men greenish sperm when they first perform ual .
