The only country in the world with actually free period products is Scotland, not the US. In the US, many states still impose luxury tax on menstrual products even though they are basic necessities. I'd recommend you read more on how it actually looks like in your country. For instance here: https://www.nursing.upenn.edu/live/news/1545-the-state-of-period-poverty-in-the-us

And why would you assume I'm American? Never lived there. Where I come from (Poland), many girls can't afford menstrual products. Many are forced to skip school because it. The amount of stigma and period poverty in so many countries around the world is terrifying. It IS a real problem.
