Giving Birth While Husband is Deployed

So I just recently found out I may have to give birth without my husband since his deployment is now being extended.. This will be our second child and all I can think about is him missing all the best moments. He’s going to miss witnessing the birth and our daughter becoming a big sister for the first time, he’s going to miss seeing her reaction when meeting her baby sissy, and so much more. We won’t even be able to to FaceTime during it & most likely can’t talk on the phone either. Luckily, I came home to be with family during this deployment but I just don’t know how I’m going to handle him not being there throughout the labor and delivery.. I know for sure that I’m going to be an absolute wreck!😭 Has anyone else here had to deliver without their spouse? If so, how did you handle it all? I could really use some tips and advice.
