Am I Wrong for being upset/angry?

Hi ladies! Looking for advice/feedback on if I’m over reacting or not...

I am nearly 6 months pregnant, I have very bad anxiety issues. My SO went out last night drinking which was fine, it was 12 and he was drunk so I told him if he needed a ride home to call, or to let me know he got home ok. I wake up suddenly at 3:30 am and haven’t heard a word. I start to have a panic attack and I see he is an hour away from where he said he was on his location, I texted and called and his phone was dead. I reached out to his mom this morning, he made home, and I still have not heard a word. Am I wrong to be extremely angry about this? I feel it was inconsiderate to not even give me an update or let me know some how from a friend he was ok or his phone died, or what he was doing. What if there was an emergency with me/baby, and he was just M.I.A while I was trying to reach him because he was too drunk and irresponsible?
