home remedies for the itch?

38 weeks and 5 days. The past week I've been having an increase in how much my vagina has been itching, last week I went into the ER because I was having so much discharge and my OB checked and said it was just how my mucus plug was coming out. But she also tested me for almost everything under the sun and all the test came back good. So I know I don't have any kinds of infections or anything like that. I think it's just how my bodies been changing, but I'm wondering if anyone has some home remedies to get rid of the itch? Please help. It's getting miserable! Sitting in a warm bath works but only for awhile before it starts to itch again!
