its not hard just tell your coach and take advil it helps me alot and your coach will understand you cant help it your getting older its a girl thing fell better hope i helped

ADVIL ALL THE WAY BABYYY!

Talk to your mom and have her take you to the doctors to make sure everything is okay.

Advil like the others said. Also, tell your coach the truth about it.

be careful with the Advil too much can ruin your liver..go see a gynecologist..then speak with your coach with more information about how she can help you..otherwise they'll probably be in the dark as well..good luck

Get your mom to write you a note. I'm sure your coach would understand, because nobody would have somebody hurt while there's a person's life in the air.(as in stunting)
