There is a company that sells ladies’ panties, in several styles (bikini, briefs, even a thong) that they claim wick away and absorb menstrual flow, feel and fit like regular undies (no bulky pad), and you just wash them out. They make ones for light days, and different styles for heavier days. Look on the internet, you’ll find them. They also make ones for ladies who “leak” a little (pee), I just got a pair and they are really nice. Another solution for expensive tampons.
