phone replaced old photos before allowing them to download.

i recently fixed an old iphone se of mine from 2022 and i use the same icloud. that phone was filled with a lot of memories from 2022 and i planned on letting my phone save the old pictures and backing up my phone (which i did back it up) but while i slept instead of downloading the old photos they replaced them with the photos i had from my previous phone and left me with like 5 pictures from 2022. is there any way i can get those pictures back? i literally backed my phone up and was purposely trying to salvage those pictures and now theyre just gone. i think maybe i didnt have enough space but i had 8000 photos and it replaced it with 10000, im so frustrated idk what to do
