When I export to a .docx file it is adding an extra blank page on to the end of my document

I completed a document in Pages. I then chose export to>Word and exported my file as a .docx file. When I open my newly created word document there is an extra blank page at the end of my document. I have tried to delete it and export again but the same thing happens. I have also tried to open a new document, cut and paste everything in and export again. When I did this it did not add the extra page but instead changed all of my formatting. Please Help!
