kinda awkward to ask but I need help...

Trisha • Been with my SO since 10-27-13, engaged since 10-20-15 I love him so much and can`t wait to start a life and get married
Ok so for the past couple months I've had this strange smell... It's almost like a sour smell and I can't get it to go away. (yes this is coming from my genital area) I've tried using summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> for a while and it doesn't seem to help. I shower every day and always wash but I can't get the smell to go away! Can anyone recommend anything that will possibly help with this or even tell me what it is? It's not a smell like a yeast infection or anything it's just a bitter smell that won't go away. Any type of info will help but please I don't want any jokes.
