iMessage Notifications Not Appearing

A few hours ago, I changed the date on my phone to 2 days ahead of the current date. After I changed it back, whenever I receive a message, the badge appears on the app, but the message notifications won't appear in the notification center, on the lock screen, or anything of the sort. I have turned alerts on for all contacts, the notifications are turned on in settings, I do not have Do not Disturb on, and I am currently on the latest IOS Update. I am looking for a fix for this issue, does anyone know what to do?
