Green, yellow , grey and white discharge too much of it!!!!

I'm 38 weeks and I'm none stop ruining my underwear and wearing pads sweating down there getting rash between my thighs rubbing and sides of my vjayvjay. To point I've had discharge run down my legs. I've got if check out so many times after swabs comes back they say it's not yeast infection or BV infection. I'm not having sex either haven't for very long time . I shower daily sometimes have bath at night don't use scent bubble baths or body washes or scented laundry detergent. I'm at a loss im hoping after the baby born I'll be back to normal down there. I'm having a c section tomorrow. I have used vagisal wash.
