Navbar Padding Btwn Pages and Searchbar

I made the search input box smaller to try to accommodate adding additional pages to the navbar (I would like to have all of the pages be on one line as much as possible). However, there is a large amount of black space between my last page (contact) and the search bar. How do I make that space smaller or get rid of it?? My site link is:

Thanks so much!
