Period mark/bullet on my home page for no reason?

Hi all,

My website has not been published yet but I have a question regarding my site.

For some reason, on my home page, there is a random, what looks to be bolded period mark on the bottom left of my screen. It follows when I scroll up and down. I have inspected so many parts of the home page and cannot find out how it got there. I am trying to remove it.

Because you can’t see my site directly, I uploaded a photo of what it looks like onto Imgur. (Photo here: https://imgur.com/a/SlPoa )

I would greatly appreciate any help if anyone has an idea as to what this is.
