Retrieve disappeared notes from iPhone 6s due to upgrade

Last night i was upgrading my notes app, this morning i open it up, it crashes. then i open it up again, and all my notes are GONE. I've looked to see if they were linked to email or iCloud, and they were not -- they were all local on my phone. i do have a backup but it is from a month ago. i have no idea how this happened, i did absolutely nothing between last night and opening the app this morning. any help would be appreciated thank you!  (iPhone 6s ios9.1) iPhone 6s, iOS 9.1
