Any ideas

I have discharge that's like toilet paper but its not toilet paper. It DOESN'T itch or burn i don't even know it comes our until after im done going pee (i check the toilet everytime because ive been having it since i had my daughter 9 months ago). I regularly treat for yeast infection just to be safe and i currently am free of any normal symptoms of a yeast infection. I get this discharge once a month in replace of my period (i have the Nexplanon implant so my period stopped). But my vagina constantly smells even after a shower and it was cleaned very well the smell started during my pregnancy and hasn't gone away since and i had my daughter 9 months ago.
