AIO - This happened tonight

My wife (35f) and I (40m) have been together for 12 years. She works as a RT at the hospital in town. Usually her shifts are 6:00am-6:00pm’ish. This afternoon she called me and said they had asked her to work late which sounds pretty reasonable for the hospital. She said she would be working to 10:30 because that is 16 hours, the most they are allowed to work per day. At 8:22pm today I got a call from her and when I answered she quickly said she has to get off the phone and would call me back. It felt odd because she called me then quickly got off the phone. I expected a call back fairly soon, once she dealt with what ever the pressing matter was, but I didn’t get a call back. When she called I could tell she had been drinking. Both of us drink so that’s not an alarm, it’s the situation as a whole that’s getting me. Am I overreacting? Is this the right subreddit? Any thoughts?
