Anyone else experience this?

I'm currently 36 weeks. For the past two days I've been feeling an incredible amount of pressure in my pelvic area it's so uncomfortbale to walk, at night when I turn to switch sides, it's so painful, all of a sudden I'm beginning to feel nauseous again, and I have the worst migraine this morning, along with feeling dizzy. 
Is this normal as I get closer to my due date? I didn't really experience any of this with my first born.
