how can i recover deleted photos from my nikon d3400?

[brenton7vargas]

I went on a camping trip and took some awesome photos with my Nikon D3400. From 03/27/18 to 03/30/18, I was browsing through all the photos I took. When I got home, I took out the SD card and insert it into my laptop. When trying to view the photos, ALL the photos from that day were gone but the ones I had before. I viewed all photos back to back but somehow from only those days it got deleted. Could someone explain to me why and how I could recover these photos if possible?
