iCloud deleted all photos by mistake

Good evening,

I deleted all my photos by mistake today evening.

I was cleaning my mothers phone, the on the same account with mine, wife and other devices.

is it possible to recover all our photos, it’s about 6000 photos?

We forgot to create a back up copy on ICloud and ITunes.....It’s a very important for us...

I hope you understand my issue....

Awaiting for positive feedback.

best regards

Igor
