Hello jodifromahwatukee,
Welcome to the Apple Support Communities!
From what I understand, it sounds like Safari is not loading a single page or multiple webpages correctly and it is trying to reload the content. In this situation, there are a few different steps that I would recommend.
First, I would recommend clearing your history and website data as described in the attached article.
Safari web settings on your iPhone, iPad, or iPod touch - Apple Support
Nest, after the data has been cleared, I would recommend closing Safari completely as described in the next attached article.
Force an app to close in iOS - Apple Support
After Safari has been closed, reset your iPhone. After the reset, open Safari fresh and use it as you normally would. If the issue continues, please let me know.
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
Have a great day,
Joe
