iMovie edit deleted original video. Can I recover it ? (iOS)

I filmed a video on my phone and I wished to edit a small part of it and have 2 different copies (1 of the full original (containing the part I took of) video and anotherof the part I took off. I used iMovie to edit the video. When I pressed done, I only had the part I took of and for some reason it decided to delete the original unedi version.

Is there a way to recover the original video?

Thank you in advance
