Broken tooth

My tooth had a cavity ((either 5 or 11) it’s on my left side)) and I got a root canal about 6 months back, I sadly couldn’t afford the crown but a few days ago I broke the tooth in half and the majority of the filling came out, now the remainder of said filling came out and the hole that had filling to what I’m guessing is my jaw came out. Just now, was not pleasant to be honest. I’m not currently in any pain and with it being a Sunday and majority of dentist and orthodontist offices being closed I’m wondering if this can wait a few days for an appointment or if I should bring myself to the ER? Am I in danger of infection? Basically what do I do now that all the filling is gone?
