Problems on Mobile Device

I’m having issues with the layout of my theme on mobile devices. The changes that I’ve made to my blog are present when viewing from a computer, but when I pull it up on my phone, I’m not seeing them. This problem just started within the past week. I have installed 3.8.1 since then as well as Jetpack. The strange thing is that when I go to edit the theme from my phone, the preview it shows is correct. But when I preview it from the dashboard or pull up the website, it is not. Help!
