Itchy omg!

So we all know where I'm referring to. This started since the first trimester I've had heavily clear discharge, since then i guess the moisture has caused me to be super itchy, I use panty liners so that it doesn't destroy my panties but even those have to be changed a hundred times, now it's getting to where it burns, so bad I can barely sit. Has anyone been in this situation? I've tried the women's cortisone nothing
