Is it my pregnancy hormones making me crazy?

My husband has a coworker leaving their office so they were having drinks at a local spot with a group from the office. It was supposed to be over at 8pm. I know how people get so I figured he wouldn’t actually be home until closer to 9pm. It is almost 10:30pm and I haven’t heard a word from him. In the past I have asked if he is out and says he will be home at a certain time to try and stick to that. If he doesn’t stick with that time I ask that he send me a message and just let me know. Since I have heard nothing and he hasn’t answered my message (just 1) I’m starting to get anxious and upset. I feel like it’s just my pregnancy hormones but he said he would be home to help get our others kid to bed. He missed it causing our daughter to cry because daddy told her he would be home.
