4 weeks and symptoms are insane, is it normal?!?

Kristin
I'm 4 weeks and 2 days and have been experiencing waves of being nauseous, exhaustion, body aches, and crazy vivid dreams. This is my third pregnancy with the first 2 being miscarriages. With those I didn't have any symptoms until week6 or 7... is this normal to feel this way so soon?!
