Did anyone else think it would feel different?

I first found out I was pregnant last week - it came as a complete surprise! I am 5-6 weeks and really struggling with how uncomfortable at night I am when trying to sleep. My body aches kind of like when you have the flu...I always thought when I got pregnant I would just feel pregnant but I just feel tired and drained...I'm worry I'm not doing a good job :(
