Accidentally shared my wage at work. What are my rights?

Location: Oregon I’ve been at a new dental office for about a month. On my first day they asked me to not share my wage with anyone. I also not get an offer letter or any hiring forms about my wage or hours. Over the weekend I was trying to apply to an apartment but they were asking for an offer letter from my job stating hours and wage to show I qualified. I didn’t have this so today I was trying to get it. They didn’t seem to want to write one for me. So I asked if I just wrote it up would they sign it. They agreed. Then I made the dumb mistake of asking my coworker if it looked okay before I gave it to the manager to sign. It had my hourly wage on it. It didn’t occur til she already had it in her hand reading and it was too late. She didn’t say anything after but at the end of the day I guess she did after I had left. Because I get a call from the dentist pissed and trying to ask me yes or no did I tell her my wage. I was terrified and struggling to figure out how to respond. I wanted to lie. I didn’t know what to do. It was too late. I never actually told her verbally but she read it. I think I’m going to get fired tomorrow. Not like I even really want to work there anymore but I need the income. I’ve never had a job where wages werent allowed to be spoken about. And I hoped she had to make more than me. But I guess from what happened she doesn’t. I was already scared around the dentist. And the manager. They have short tempers and the littlest thing I’d do I would get snapped at. How they offered me the job was really weird too. Now I’m wondering. What’s the best way to go about this if they do/don’t fire me?
