WELL, Ive Been Taking Antibiotics For A Strep Throat. So

WELL, ive been taking antibiotics for a strep throat. so I don't know if I have a yeast infection or if something down there isn't right. Brown spots has been in my underwear for the past day or so. Then when I took a closer look I saw that brown goo was coming from the inside of my vagina. I looked at my labria minora and on the right side it was bigger than the other and the skin was also brown. I don't know if I should be worried. I was told that this could happen if you had rough sex, but ive never had sex, nor have I ever had my period. please help, im kind of scared to tell my mom.
