Feel sick

I've honestly had a very easy pregnancy. I didn't have any morning sickness (ever) and I've gained 5 pounds my entire pregnancy. Well, I'm currently 36.3 weeks and I feel like crap! Especially when I wake up in the middle of the night. It's a mix of feeling nauseas and achy....kind of flu like. Is this normal towards the end??? I feel like my good luck has run out haha. Ps, I have no signs of labor (not dropped, not dilated, nothing!)
