All my tabs are gone after an OS update

I have over 200+ tabs open (don't judge me, I was dealing with something personal and like the chaos) the night before, but the next day it's all gone. I thought that it would all be in the recently closed section but they're not. And this was after an update. Now I lost every tabs with no idea which ones were open since they're clearly not in the recently closed tab. I thought about the backups but the problem is that the last time I backed up my iPad was a month ago? Maybe even longer? And I can't afford to lose anything more now.
