Ask your grandmother how she or her female ancestors handled having periods while poor. There are solutions, have been for millennia, so cut the bullshit about how menstruating negatively affects the poor. It’s a normal biological function, not something weird or unnatural. Also, only girls or women have periods. You must have two X chromosomes (XX) to menstruate. A girl is a juvenile female human; a woman is an adult female human, both having XX chromosomes and sexual characteristics consistent with human females, you fucking dolts. It’s not hard, even toddlers understand this.
