Wash Rooms in Schools

I am in Lilian and I am 13 years of age in std 7. Next year i am going to class 8. and finally do exams. The only problem is that i come from a poor family. My parents sometime can't afford sanitary towels. one day i went to school and i had nothing to detect. I was caught up in a situation in class where by my uniform was messed up. I become very shy even to and when students went for break time i ran from class quickly and went back home until that period ended. After comming back  i never imagined what other students will say about me because i had left marks on my desk. my home science teacher counselled me and decided to give me sanitary towels one of the N.G.O. was disturbing to girls in school
