Ultrasound scheduled for 3pm today..and yet..bummed

Well, last night I got home from work (Mondays I always get home an hour before hubby) and when hubby got home he told me he had to call his dad (who he works with on tues and wed) because he signed up to work OT at his other job, which pays much better. He calls his dad and his dad has to be the one to tell him "Brian, isn't Steph's ultrasound today?" The look on his face when I walked outside apparently as his dad was telling him, because I was also going to tell him was almost as if something had just clicked in his head. I was so upset that he signed up for OT. Because its not mandatory but he wanted to work to make extra money.
So, I will be going to my 12 week u/s today without my husband (my step mom in law is going) and I called me mom and even she isnt coming. I guess I was just majorly bummed and did a lot of crying last night because it was very upsetting to me.
This is our first child..and I reminded him sunday night, how could he forget!
