Genital area smells??

Alisa

I only wash with water around my vagina I try to be extra careful with it but recently I’ve noticed the skin around it just like my clitoris and the skin around that. Even after a shower it doesn’t smell better. I am very hygienic and when something like this happens it makes me really insecure. How do I make it better ?? What is causing it ?? It’s JUST the skin not the inside of my vagina that smells. I’m also 20 weeks pregnant
