OK I am 16 year sold, and i am not sexually active, i've had yeast infections before that just seem to come back, but now thats gone and i have this redish brown stuff with a fishy eww strong smell. i don't know what it could be and it bothers me because when i go to the doctors they see no sign of anything and as soon i get home theres junk in my pantyliners. i also don't have regular periods for months now, they say it normal but once i turn 18 it will be a concern. i do play many sports and wear tight fighting clothes in the events, cheerleading gymnastics and tennis, shorts and leotards, not by choice. i would really just like to know whats going on. i would for once like to be able to wear underwear without having to worry about weird junk with smells coming out of me, i feel gross.
