So tired

I’m 21 weeks and so tired in the mornings. I have a 3 1/2 year old girl and don’t remember being so tired with her pregnancy. But of course I didn’t have her then. With quarantine I have been home with her and been able to take it easy in the mornings. I start back to work on Monday and need help! How do you’ll get up and get going?? Before being pregnant I did coffee but trying hard not to drink any caffeine. By noon I’m wide awake it just getting there that’s hard.
