I feel like I never sleep anymore

I've been up since 4 am and I hate it. I had broken sleep all night, woke up in a sweat 5 or 6 times.. now it's 7 am, I'm wide awake and still I'm exhausted. And when I finally do sleep I have crazy weird dreams and I don't dream ( atleast I don't remember them) oh pregnancy... I can tell we are going to be good friends.
