The school nurse is teaching a group of middle-school students about the female reproductive system. Which statement by a student most accurately describes the reason menstruation begins?
 
  1. Your uterus starts to contract, and this causes the lining to come out, which is your period.
  2. Your brain sends a signal that there is enough estrogen and progesterone. Then these hormone levels drop, and you get your period.
  3. You have to have your period every 28 days to be normal.
  4. You get your period when you ovulate.
