Can’t sleep !

Hello ladies I’m 5 weeks pregnant and I just found out I’m pregnant on Saturday and oh my gosh I can’t sleep ! And when I do fall asleep I only stay asleep for 5 hours or so it’s driving me crazy.. and I work min-fri 40 hours a week I need my sleep . Lol is this normal my first pregnancy was nothing like this I slept fine I’m not sure what’s keeping me awake any ideas ?
