34 weeks pregnant and extremely tired

Hey ladies, I know is normal, but wanted to know how you all are dealing with this. I'm 34 weeks pregnant and for the past 4 weeks km just exhausted. My work reduced my hours so I could get some rest 4 weeks ago, from everyday to 3 times a week. My issue is that my tiredness is so bad that every time after work when i have to drive back home (1hour) and I find myself falling a sleep, my eyes feel so heavy, I have to call my hubby to talk so I won't fall a sleep. I just cant drive. I still have around 2 to 3 more weeks of work. How can I handle it? I drink coffee. Go to pee every hour😩 and my back is in so much pain. Plus I have my 2 and a half year old, which now she is been very teenager behaviour lol.
