can i file a mechanics lien whithout a premilinary notice?

I started a project over more than 45 days ago, I did not send an initial preliminary notice. I am also a contractor, the contractor has not paid me, I do not have a written contract, however I have documentation that shows I was hired and agreed rates for the project, text messages and partial payment. I live in Minnesota. Can I still fill and send the lean claim, because the house that I did the job on is currently in pending status?
