In the spirit of all ladies who shed their uterine lining (mine is shedding as I type these words!) here is a series of images by the poet Rupi Kaur.
"i bleed each month to help make humankind a possibility. my womb is home to the divine. a source of life for our species. whether i choose to create or not. but very few times it is seen that way. in older civilizations this blood was considered holy. in some it still is. but a majority of people. societies. and communities shun this natural process. some are more comfortable with the pornification of women. the sexualization of women. the violence and degradation of women than this. they cannot be bothered to express their disgust about all that. but will be angered and bothered by this. we menstruate and they see it as dirty. attention seeking. sick. a burden. as if this process is less natural than breathing. as if it is not a bridge between this universe and the last. as if this process is not love. labour. life. selfless and strikingly beautiful." - Rupi Kaur
