Identifying if this is Blueberry or Deerberry

I found this growing, just now. The app on my phone gave chokecherry, deerberry & several types of Blueberry as the result. There were always chokecherries back here & I attempted to scattered seed of the other two the last couple of years, which seems to have proved thus far unsuccessful. But, for such a small specimen, the leaves are about twice the size of those of the plants I know from memory are chokecherry. I tried a result on a different young plant & it retained chokecherry in the results, but not the other two. I know it's hard to tell from the pic off my crappy phone, but the leaves are very finely toothed.

On a chokecherry there is 2 tiny little glands at the base of the leaf.

I only just got a chance to check as I was trying to get my bare root Skunk cabbages out. This plant does not have any sort of structures between the leaves & the stem, so hopefully its either the deerberry or blueberry. Thank you for the tip. I'd just about given up hope that any of those were ever going to grow.
