infection or normal?

So I’m 14 and started my period when I was 11. Ever since then I always have discharge which I’m almost certain is normal but (bare with me this might get a little personal) I guess you could say I have a ‘strange’ scent down there. It’s not terrible but it doesn’t smell like roses (I know I know, EXTREMELY personal) my discharge also has a scent to it. Anyways I just want to know if I should be worried at all or if it is infected & how to treat it. I really dont want to go to a doctor for it but if I absolutely have to it’s whatever. 🙄🤦🏼‍♀️
