Fatigue symptom?

Usually I can stay awake the whole day. I'll feel tired and whine about how tired I am but I can do it. For the past few days though I seriously need a nap or I won't make it. I take a nap and after I wake up I still feel exhausted and need to sleep some more. It's affecting me at work because I'm not as concentrated and right when I get home I need to sit/lay down and just rest before do in anything else. I feel so lazy and unmotivated.

My marriage is fine so it shouldn't be depression, I feel fine. I feel like my life is actually perking up a little so I shouldn't be anxious or depressed.

I want to know, is this the fatigue symptom for pregnancy? I've never been this tired. Like after this post I want to sleep again 😂😴. Should I be concerned?
