Please help. I don’t know what this is...

Hey everybody. So a few weeks ago, I started getting excessive yellow discharge, like a lot more than usual. I figured it was just a new way my body was getting ready for my period, because this had never happened before. I waited it out until my period. I just finished it yesterday but the discharge came back. I don’t know why. There’s no pain, itching, or irritation. There is a slight odor, though. I tried researching it but it was either talking about STIs or yeast infections. I’m a virgin and I’ve never had a yeast infection so I really don’t know. Please if anyone has any thoughts, let me know. Thanks!
