Discharge

Okay so quick question. My vagina doesn't have a strong Oder but I definitely notice it like just as a thing that and individual notices about ones self. I don't think other people can smell it but I mean it's not like anyone has ever said anything. Plus people normally tend to be around me and like near that area and not show signs of discomfort near my body ( I'm a people reader) but anyway, it's a musky smell that kinda comes and goes but more than less. I'm a virgin and not really sexually active so it's not from that. I try to eat clean and drink lots of water. Idk I'm just curious as to why I have this smell. And what can I do to treat it?
