help!

i am 14 and i've noticed for about 2 years my vagina always smells weird unless i just took a shower. I sweat more then normally and i'm wondering if that's the reason. I'm too scared to go to the doctor and i've told my mum about it...kinda and she just said its supposed to.

At the start of the year (2018) i finally shaved my vagina and for a couple of weeks it actually smelt good and i thought it was just the hair. But now when i shave it still smells and it's worse on my period.

Some days it smells really bad if i have sweat a lot but sometimes i don't sweat nearly at all and it only smells a bit. I've never had sex. I'm worried that there's something wrong. The smell transfers to my clothing and i get self conscious. I don't know if its a fishy smell or not. I'm mostly concerned because my friends have told me theirs don't smell bad.

Sometimes it's so bad that i have to spray my clothes with deodorant or even spray around my underwear just so that i don't smell it. Please help. I don't know what it is.
