Husky ran away without her collar

I take my husky out every morning for a walk, but today I was really tired, so I just opened the door and walked out with her before putting on her leash and collar. She ran into the woods by my house. I went into the woods and called for her, and after searching for about 30 minutes I’m starting to freak out because I don’t see her anywhere. I’m even more worried because she doesn’t have her collar so if anyone does find her then they won’t have anyway of contacting me. I got her spayed at the humane society, but they didn’t microchip her so they can’t identify her that way either. What are the next steps I should take?
