Is it normal to be itchy while pregnant?

Hey everyone! So I’m currently 34 weeks +4 days pregnant. I’ve been dealing with an extremely itchy upper back ,up on my neck and to my left shoulder since last night. There is no rash, no redness or any bumps or any kind. The itchiness isn’t getting better or worse but it’s driving me nuts. This is my third pregnancy and have never had something like this happen before. Is this normal or do I need to call my L&D and get myself look at? Thanks
