For a few weeks now i’ve been getting a strong odour down below (im a female)

I’ve done a STD test and it all came back clear. I wash every single day so my hygiene is good.

I have used fem fresh soap down there before and shower gel (only around my vagina NEVER inside) i mainly have showers but when i do have a bath it’ll be a bubble bath. I’ve been with the same partner for 5 years! The smell is that strong i can sometimes smell it through my jeans/leggings, when i wash everyday the smell doesnt go, when i go to the toilet i can smell it as soon as i pull my knickers down. It makes me so self conscious about having sexual intercourse with my partner because i always think “can he smell it”.

Its really not a nice smell. Even though i wear knickers with my jeans and leggings the smell goes onto my crotch area of my trousers.

Im going to ring my doctor in the morning!! Does anyone know what this could be please ?
