I'm really worried

My husband was offered a job at a distribution center. And I believe on the app we told them about his misdemeanor charge for marijuana, which he no longer does. But now that we're waiting on the background check to come back I'm so worried I don't know how to handle myself. I know this isn't good for the baby at all, but I can't help it. I'm praying so hard that this works out for him because he's worked so hard to get here. He already did the drug test, which shows he's clean. I just don't know how to stay calm right now.
