All of my messages deleted randomly

All of the texts in my messages on my iPhone randomly deleted today. I just went and opened the messages app and it was completely empty. Is there a way to restore these messages back to my phone? I've tried signing in/out of iCloud, turning messages on/off, restarting my phone, etc. These messages are still on my Mac and iPad though, so I know they aren't gone. Is there anyway to restore them back to my iPhone? Doesn't iCloud save messages in backup?

Thanks!
