Morning Glories: Is this Bindweed?, 1 by Hillbilly_Gran

This has been growing on my kennel fence for sometime. Just assumed it was the wild blue morning glory that is abundant here. I do have what we refer to as Bindweed, but the leaves are different. The flower itself is about 3/4 " wide, which made it difficult to get a focused photo with my dinosaur digital camera. It is the first time I have seen this particular plant here. Any help with an ID would be appreciated.
