Dilemma!

Hi everyone! So I have a bit of a dilemma I would love feed back on. My first prenatal appointment is next week, December 20th. They will not be doing an ultrasound at this appointment. My husband leaves for 6 weeks for military training the first week of January! I will be about 15 weeks when he returns. I hate that he might not be able to see our first ultrasound in person and hear the heart beat before I announce the news on social media (we both have huge extended families and this will be our way of making sure everyone knows the good news). What would you do? Would you take a video of the ultrasound so you can record the heart beat? I don’t even know if he will be able to use his cell phone at all during this training. I don’t want to offend anyone, especially my husband!
