When deciding what to sync on iCloud, upon disabling calender I accidentally hit delete on iPhone too, is there any way to get my events back?

I was on settings>iCloud and turned off calenders, I then meant to hit keep on my iPhone but accidentally hit delete from my iPhone and now most of my events are gone, is there any way to get them back? Thanks so much 🙂

I also have another problem that happens occasionally on the calender app, when I'm trying to scroll down it sometimes makes me jump back and makes the days very hard to navigate.

Thanks!

Kind regards, s.s.9.9
