don't feel pregnant!

Does anyone else not feel pregnant even tho they are? I'm 5w 5d and other then the obvious sore boobs and need to wee more I keep forgetting I'm growing a child. With my first I had terrible sickness every day but nothing at the moment. I was talking about Christmas with my oh and he said about having prawns for starters and I got really excited to then be reminded that I'm pregnant and can't have shellfish haha! Anyone else? I kinda want all these symptoms so it feels more real!
