Retainer is shifting my teeth the wrong way..?

Got my braces off today & when they gave me my retainers they had to adjust it cause it didn't fit right. I noticed tonight that its pushing one of my front bottom teeth back slowly. I looked at the wire & its not a perfect round wire, there is a slight bent on the side where the tooth is shifting. I know for a fact that I didn't bend it, it was my ortho. I don't want to wear it if its making my tooth be pushed backwards. Do you think I should wear it? I'm going to the ortho tmrw, even tho I don't want to -___-
