Deleted the notes app

Hi

I accidentally deleted my notes app from my Iphone, so i had to reinstall it in AppStore. I now have lost all my "on my phone" notes. I would really love to get them back. I've tried to reinstall a backup fra iCloud, but it is like there isn't any, even though i says "backup fra today 22:14".

Have someone tried something similar and maybe know how to fix it?
