Am I overreacting?!

So, I'm currently 39w and my fiancé is currently deployed. My mom and I are very close and she has been my number one support system throughout this pregnancy. She asks to come to all of my appointments, check-ups, etc. and I genuinely appreciate her but of course it's not the same as having your SO with you. Today, I went to L&D due to some spotting and decrease in fetal movement. My fiancé always tells me to call him if something happens b/c he knows I could go into labor any day now. So, I let him know I was going to the hospital but guess what, he didn't answer any of my calls. Two hours later, when they're letting me go home because my NST was normal, he calls and tells me "sorry" and doesn't really have a reason for not answering other than he was "driving" ... Yes, for two hours... And so I let it go, and about an hour later I call him from home, he doesn't answer again but sends me a photo of him at a hookah bar with his friends, saying "We are just chilling." I didn't even reply because I just feel aggravated and I'm not even angry that he's out.. It's just the fact that he's constantly telling me that he wants to be here for me, supportive, etc. but then does shit like this. Idk, am I overreacting or do I have the right to be upset?
