Smell down there

Kind of embarrassed about this, but recently I've been having kind of a lot of discharge and no matter how often I wash it, down there always seems to smell. I do not go to a doctor, because I'm 17 and my mom isn't that cool with me having sex. my boyfriend of over a year and I ALWAYS make sure to use a condom and check if once it's used. Any advice on what it could be/what I should do?😰
