6 weeks and fatigue most of the time, normal?

God girls, like I’m good for a while and after I need to take breaks where I need to lay down because I’m exhausted. When I take a long shower for wash my hair, I finish and I feel soooo exhausted. After work I’m totally dead!!! I even want to start working out easy, but man! I don’t know if I can do it. How do you guys feel? Is it normal to feel that exhausted for a while??? Is it gonna be only the first trimester??? I have so many things to do and I can’t keep up with myself! 😑…
