My 16 year old daughter has become sexually active within the last 3 months. She says her boyfriend used a condom. Her periods have always been irregular. She hasn t had one since May, but has been negative for pregnancy tests. She has been spotting for a couple months, and for the past few days has been spotting, has had vaginal itching, burning, especially when urinating. Until I can get her to the doctor, what could you recommend she do to relieve these symptoms?
