Improv of "Wishes for Sons"

I love the line "wish them one week early." I thought about how in the poem, the speaker wishes this on her son, but in a different context, it could be wished upon other females...

I suffer silently in the last stall
of the basement bathroom, padlocked 
in by the cheer-leading team.
Their perky wrinkle free
skirts, blindingly white,
even in the red of the month.
The rest of us wish them one week early,
but their arrogance in the universe
grants them a tampon from the sky,
and identical white skirts,
freshly pressed in the lost and found.
