Soooooo tired

First time pregnancy here ! I'm almost 7 weeks .... I can't seem to keep my eyes open! I'm normally never like this , but now I get a full nights sleep and STILL nap after work. I feel I'm dragging ass all day long . I hate it . Is it normal to be this tired ? Any tips on how to combat it ? How long does this part last 😫 I feel like I'm falling behind in everything because I have zero energy , I wasn't prepared for this ! Excuse me while I go nap again... lol
