Private Part Odor

Sheena
Hey Girls, 
So this is quite an embarrassing question but here goes. So I'm 17 turning 18 in a couple of weeks and I have this Odor problem. There is this weird Odor coming from my vaginal area and I'm getting annoyed by it. I took a bath 4 hours ago so I don't think hygiene is an issue ( I also change my underwear nearly everyday, I even wash my private part whenever I go take a pee) I don't know what the issue is. Any kind of help would be appreciated xx
