Do you think 27 weeks is that "far" along...?

I am 27 weeks pregnant with my second and I feel like such a baby! I am not a complainer by nature, so I keep my whining to a minimum. But my back hurts, my hips hurt, I waddle and I am slow moving. In my head, I think I am only 27 weeks, I should not be feeling this way. With my first, I do not recall feeling this way with my first. Do you think 27 weeks is that far along?
