Since you suggest you never used My Photo Stream, nothing will happen to your photos anyway.

No. If you never had photo stream turned on then you have nothing to worry about.

I just want to add that even if you used photo stream, you will not lose the photos on the device on which the photos were taken. They will remain in that device but will disappear from your other devices.
