Hi, I'm just 19 years old and had yellow discharge since a year ago, no itch no clumpy material and no smell. Can somebody tell me what's going on ☹️, I only had two sex partners, no foul smell just one light kind of vagina smell. My pantie liner has to change like 7/8 hours or it will stain on my panties. What should I do? I'm going through full body check up now.
