Vaginal oder

So my ive always had a decent amount of discharge, but only every now and then there is a smell with it. the smell is never too bad, but sometimes it gets worse but mostly theres no smell. no other abnormalities like itching or burning when i pee. Is this something i should get checked out or is it normal to have oder occasionally?

if you discharge look like cottage cheese its a yeast infection , if your genital has a fishy smell its vaginosis bacteria, if your discharge are green its gonnorhea and if its burning when you pee its chlamydia
