I have worn tampons for about 9 years now I have no children and for some reason my last two periods when the tampon is inside pee soaks up and eventually wets my underwear and my pants. I can't feel it. It usually just feels like my tampon is filling up so its time to change but when I take it out it's not full. Yet my underwear are soaked with a urine smell! This is so embarrassing I'm not sure what's going on I've never heard of this.
