Anyone else already feel like they're experiencing clumsiness/forgetfulness??!

I'm a little over 6w and I'm SO forgetful. I forget to do things at work. I forget to schedule appointments. I forget about exams (I'm a college student). And I just scheduled an appointment for the time I have class tomorrow, completely forgetting that I scheduled it for exactly when I would have class. Is this normal???! I've also been extra clumsy. Knocking things over. Sometimes I almost feel like my hands/feet don't make the connection with my brain! Lol.
