Rant plz read

So I'm 7w4d and I have my 1st ultrasound tomorrow and my so was there when I made my apt so he knew we had this apt way ahead of time and he didn't tell his job that he needed this day off. He has to work tomorrow and I got upset and he thinks I'm over reacting. Hes acting like this is not a big deal when I feel like it is. Am I overreacting or is he just being a jerk?!
