How Long To Wait to Contact Hiring Manager After Phone Interview?

Here is my situation. I had a phone screen last Thursday with the Hiring Manager of a company I'm looking to join. She then moved me on to the next step, which was me talking with the supervisor for the position, the next day. Both the Hiring Manager and the Supervisor said I would be hearing feedback from the Hiring Manager on Friday of last week or this past Monday. I reached out late afternoon on Monday to confirm the call, but so far I haven't heard anything. How much time should I let pass before I try to make contact again/ should I make contact again?
