So, im 13 years old, never had sex before, never had my period, but im kinda worried because there is this white and clear, sometimes a little yellow stuff in my underwear. Sometimes after school there is so much of it it makes my jeans damp. i dont know what to do. Its not urine at all because it is thicker. i have just been putting a wad of toilet paper in my panties before school or before i go to bed. should i be worried, what is happening?
