Deleted photos from my sd card by mistake

So i have this Sd card to Phone camera card reader, you out the sd card in and connect it to your phone, it pops up in the iPhone photo app as “imports”, and you click on the ones you want to import and they do.
The thing is, i had some images that i already imported and it gave the option of “delete imported”, but when I did that, it deleted all of them, even the ones that weren’t imported yet. Is there any way to recover those photos? I stopped using the sd card and put it on the side, I’m currently on a trip so I don’t have access to my laptop currently and it will be another 2 weeks before I get back.
