Should I be upset?

My boyfriend hasn't been to one of my appointments. I try to schedule them around times he will be out of work and he still finds excuses not to go. I know that there are other things going on but I think he should have came to at least one ultrasound. Am I wrong for being mad? 
Also I forgot to mention this isn't his 1st kid. He has been through this before and he is treating me differently. 
I'm not asking him to come to every appointment. Just some of them. It sucks to be the only woman there alone. Almost everytime.
