Why does it smell bad

Hello everyone please don't think this is a joke or anything because I'm literally dying to know what is going on . I'm only 19 years old ! And my vagina smells so bad ! I have no idea what's causes the smell I shower twice a day and clean with wipes . There's times I leak even a little and the ordor goes through my pants and I can smell it . I'm barley going to see a doctor about it but I read online that girls who have the same issue can sometimes be told there is literally nothing wrong and it's like it can't even be fixed . I have an idea what it could be and I wanna know if anyone has noticed the same ??? I'm on birth control and my boyfriend cums in me during sex and I feel like I wash it all out but maybe i don't and that's what's causes the smell after a few days of leaking ? I have no idea because sometimes we only have sex once a week but like two or three times In that day. So in within that week I can't tell if it is the cum cause can it really still be leaking for that long ?? Please help !
