Have you ever had to do an emergency wash at 10 p.m. because you ran out of clean period underwear mid-cycle? It’s the most common mistake when starting out: buying “one or two to try” and running out of clean underwear halfway through the week. Here’s the real calculation of how many pairs of period underwear you need<\/strong> for your type of period, without overbuying or falling short.<\/p>\n\n

The basic rule: think in wash cycles, not period days<\/h2>\n

The most common miscalculation, and the one that frustrates beginners most, is counting only the days your period lasts. But period underwear, like any underwear, needs a wash-and-dry cycle between uses: usually 24-48 hours if you wash it by hand and air-dry it, which is what’s recommended to avoid damaging the absorbent layer. So the real calculation depends on three things: how many days your period lasts, how often you want to change, and how long your washing machine (or your drying rack) takes to give them back clean and dry.<\/p>\n\n
