What if a girl's vaginal fluid is red?

Serious: Normally at the age of 12, girls will start to have periods. Girl's bodies make beds inside them for the babies, half made of blood and the rest, water. After a period of time, the body lets out that bed and creates a new one. To be warned, girls will have PMS before (pre-menstrual syndrome/stress) periods, so watch your step! Joke: then the painters are in!
