Should I be annoyed or am I just hormonal?

So I'm due next Friday and my husband decided to go out to dinner with 2 co workers tonight. Said he wouldn't be long at all, and I asked him to please not drink a lot, since I've been having a lot of cramps/pain and there is a possibility of me going into labor at any time. We live an hour away from any family so obviously he's the one that has to drive me to the hospital if anything comes of the pain I'm having. Well nearly 3 hrs later I text and ask when he'll be home and I get "on my last beer" 🙄 am I just being hormonal or am I justified in being annoyed right now?
