I'm a week late on my period and have white discharge my last period i had came in 2 weeks late i had a burning sensation and a brown discharge

Testing: I am first wondering if you're sexually active and if you are if you are using protection. You could be at risk for an STD, thus the white discharge.If not, the white discharge could still represent some kind of infection like a yeast infection or bacterial vaginitis. You should see your doctor to get tested and treated.Irregular periods are not abnormal at your age but be careful if you're active
