Not sure whether to be excited or nervous (PT related)

I was Skyping with my parents and LO-- LO ran away after a few minutes, as usual. I kept talking for about 2 minutes. I heard a flush, LO then came in and said, "Mama! Poop!" I asked her if she went in the potty. She said yes. I checked the potty-- but she had already flushed. Then I checked her butt (gross, I know) and she had... residue. So I think she went all by herself!! I am so excited, but I also have a fear that I'm going to find a pile of poop in my house somewhere.
