YEAST INFECTION HELP

I'm 13 and have a yeast infection... I need to get some meds. Idk how to tell my mom. She warned me I'll get an infection because I wear my panties up to 5 days oops!! I only have enough to last me so long so I have to wear them a certain amount of time if I want any "clean ones". Are there any home remedies I can try? I just can't tell my mother. I have a horrible relationship with her. Please HELP!
