Hey, my period normally starts in the late night or sometime in the morning, my period still isn't regular but i know its coming soon. i've been getting my period for about a year. i know we're not supposed to use a tampon with out your period, i have swim practices every morning, most of the time, I'm not really swimming but sitting and waitng for the rest of my lane to come, what will happen if i get my period in the water, and what should i do!!
