Found Eggs On Glass!

so I have a 5.5g with 7 ember tetras
And I have twp pest snails. I know I only have two because I purposely put them in there. They are super tiny.

I found these eggs on glass and I can't figure out if its from the snails or tetras. My first guess was snails but I have only two there and one I put in today before I noticed the eggs and like I mentioned they are both very tiny so idk if they reproduce that tiny (then again they are pest snails so they might)

What do you guys think?

 

Those are definitely snail eggs!

 

Snail eggs.

 

Ok thanks. How can you guys tell?

 

because that's what ramshorn eggs look like. assuming your snails are ramshorns.
