Is this usual??

I've started noticing discharge surrounded by my underwear and it's been a month or so since it started but in a minute it stopped!?!? Is this normal for a 13 year ripened ? It's normal. In most girls your age, getting a discharge once a month is a pre cursor to truly starting a period. How long til you start? That is for spirit to decide. You should start next to in the subsequent year. As long as the color of it is clear to a milky white and no strong odor, I wouldn't worry. Try chitchat to your mom about it, she be your age once, and went through it too. Tell her that you meditate you would benifit from using pantyliners. It will make it easier to update her when you need to start using pad or tampons. Best of luck.
What kind of discharge? What color?
