They are already fertile when you're born, but not released until menstruation!
Puberty triggers all these developments. Menstruation shows that you are fertile and capable of reproduction.
The onset of menstruation is the biggest thing. This signals that the ovaries are now fertile and capable of bearing a baby.
If you are having menstruation, you are already in puberty. That's the definition of the word.
because puberty starts at the age of menstruation, that is the age at which the body is developed enough to begin with the job of reproduction.

Menstruation typically begins in either late Tanner stage II or early Tanner stage III of puberty.

Menarche (first period) is part of going through puberty. Menstruation only occurs when a person starts to ovulate, as menstruation occurs if an egg isn't fertilised. Puberty refers to the process of going from a child to a sexually mature adult, thus puberty has to start in order for you then to start menstruating as menstruation occurs only after you start to ovulate.
Kinda-sorta. If you're otherwise healthy, puberty is when you become fertile.
