My first official ob appointment is this Friday.. I'm starting to get nervous. Idk why, but I'm afraid we won't hear a heartbeat and our baby won't be in there. I haven't had any bleeding or anything that would cause me to worry.. we have just had so much loss and disappointment this last year I feel like it could all go away again at any moment. I think I'm having a crazy prego moment and my mind is just running wild on me. Wish my husband didn't work nights on days like this..
