Thanks, I've spent Christmas alone before this one just hurts a bit more. It's our first year married and now I am pregnant.
I'm sorry. I know it seems like the end of the world right now, but can you skype or facetime with him on Christmas Day? The first appointment is usually just taking history and peeing in a cup. Nothing terribly interesting or exciting for him to miss. He'll be able to come with you to other, more exciting appointments, don't lose heart!
You'll make it. Take a warm shower, pamper yourself with some lotion and a warm hot chocolate or apple cider. Then curl up with a book/movie and go to sleep.
