seedling identification

I am trying to determine if these are sunflower seedlings. It has been a little over a month and I don't believe that there were any other seeds in the pot at the time I planted these seeds. (I planted 4 total)
I looked at photos of different types of sunflower seedlings, but I am still unsure.

The Lemon Queen seedlings

The Lemon Queen seedlings will have a dark stem and two lobe-shaped leaves to start. They'll get about 2" tall then put out a new set of leaves. Can't see your photos.
