Uhm, About three-four days after my period I have been getting discharges. First it was a dark brown after my period ended, then sort of light brown, then after it turned light yellow.. And this light yellow discharge has an odor. I've done some research online.. and I'm afraid if I have a infection or std.. I have had sex but only with one partner and it was always protected. What could this mean because I don't want my mother to find out?? :(

My vagina does not itch and is not sore in someway. It just has a light yellow watery discharge that smells funny. But then again it can smell cause I don't regularly wash "down there".? Im soooo confused and frustrated. PLlease help.
