Itching & Swelling (sorry tmi)

I'm 38 weeks and just now started having some itchyness at the beginning of the week..of and on and usually would go away after a shower. I can't go a day without taking at least a shower in the morning and before I go to bed simply because of the increase in discharge which I know is normal. It's not a yeast infection so I'm trying to find a natural remedy that will help with the swelling! It's making me miserable and I really don't want to go into labor with this problem, it's only gonna make it worse 😩 Applying ice helps a little but still doesn't make it go down. Someone please help!
