@Shash01: Please can you confirm the model number and current Android version of the device you're using, located in Settings > About phone (Android version can be found in Software Information)?
Have you recently switched devices? The layout of the Messages app typically shows the messages and conversations in a list, with the most recent messages/conversations at the top of the list. Is this not the case? If you have any conversation categories set up, then try tapping on 'All' in the top left of the landing page to display all your messages, as per the above.
To give me a better understanding of your issue, are you able to provide a screenshot of what you're seeing, and attach it to your next reply?
I've not switched devices but noticed the look changed when I was in Egypt last week? Don't know why that would change it ?
@Shash01: Looking at your screenshot, the layout is as expected, although it does seem like the font is larger than average. To adjust this, please head to Settings > Display > Font size and style, and adjust the slider at the bottom of the screen. To unpin a conversation from the top of the Messages app, press and hold on the conversation > Tap 'More' in the bottom right > Unpin from top.
