There's a chronological gap in the photos that had been backed up on my iPhone's camera roll?

I dropped my phone in water and had to get a new one. Of the photos I was able to recover, there's a gap in the time the photos were recorded… So I was able to recover older photos up to a certain date, then about a 5 month gap, and then photos from the end of the gap to a date pretty close to when my phone broke. I don't understand how the more recent photos could be backed up, but not the one's from the gap. Can anyone explain this and is there anyway to recover the missing photos?
