ok so i was swimming in my neighbors pool the other day (i had been completely through with my period for about a week) and i wasnt wearing a tampon or anything...but i felt a sort of discharge type thing and so i looked down and there was a little brown splotch on the pool floor....well it wasnt tiny...but it wasnt like HUMOUNGOUS...and i know it came from me because i walked in front of me and a little more fell down but it was just a little...will that happen again??? when i go swimming??? will i just randomly have little discharges in the water when im not on my period???
