Being sporty does not affect your period etc, and neither does being short. It is normal to get your first period between ages 9-16, so height does not affect your period, and being sporty does not affect your period.
No, it can't.
Just exercise more.

Yes, being sick can affect your menstrual cycle by making your period late. Stress, whether good or bad, can have the same effect.

It's called being underweight or too skinny.
no you cant die from being skinny but you can die if your to skinny if you think your to skinny you should ask your doctor you never know it might save your life.
Being skinny, or losing a lot of weight, shouldn't affect your menstrual cycle unless it's a very drastic change. When you become very skinny, your body decides that it's 'not fit' to have a baby, so it halts the production of eggs, and hence the uterine lining, which is what you shed (blood) during menstruation. No eggs, not uterine lining, no period. So unless you lost A LOT of weight and were OVERLY active, odds are you wouldn't have any problems.
