How many pads/tampons a woman uses depends on her flow. A period can last anywhere from 2-7 days, give or take. Heavy flow days can require a pad every couple hours, more or less, where as a light day could only require one pad for the whole day. Tampons are different because they have to be changed regularly, having them in for no more than 8 hours because of TSS. Additionally, some women wear a pad with their tampon in case the tampon leaks, which could contribute to costs.

Thanks for the info. This is pretty similar to the responses I’ve seen in the thread, and it sounds like a period costs could be around $5-20, roughly? This is not an insignificant amount, and I can see how it can seem like an added burden on top of the physical symptoms. Having a monthly period honestly sounds slightly horrifying.
