Awful Discharge! 😩😱 Help!

I'm too embarrassed to ask my mom about it so please help. I have been uuh whats the word "secreting" a lot of discharge. This has been happening for months now. My undies would be soaking with discharge sometimes even up to my shorts or jeans and it has an unpleasant smell. Sometimes the smell is so strong or I secreted so much that while just walking or standing like I can smell it. It stops my hubby from going down on me sometimes coz it smells really awful. One time it smelled so nasty during sex that I was literally gagging. I dont know what's going on down there! Any advice? Help!!!
