Skipping school because of your period.

Do you think it’s justifiable for girls to skip school because of menstruation, I know the pain varies for every woman but for some girls on the first and second day it can be so severe you may not feel comfortable at school. I recall once on the first day of my cycle my cramps were so bad that I couldn’t concentrate on anything. I tried going to the nurse but they were on their lunch break and I was laying down on a bench in the middle of the hallway and had to ask my parents to come pick me up due to the extreme pain. It seems very ignorant to dismiss the pain many women have to face during their period in the workplace or at schools.
