I get spanked almost every month when my wife is on her period. She is more irritable and for some reason I am more annoyed with her. However, pertaining to the topic. My wife has these period underwear from a company called Thinx. Basically they are underwear that can either be used as backup to a tampon or pad or be used in place of a tampon or pad. She even has thong underwear from this company for the last couple days of her period. There might be something to consider. Thinx.com is the website.
