Extreme fatigue at 22 weeks? Anyone else experience this?

For about 4-5 days now I've been experiencing extreme fatigue that is getting worse. More like all day feeling weak and tired and having to take naps/ feeling like simple housework or walking around the grocery store is way too much for my body. I want to get out and do things but everything feels like way too much. I find it super hard to muster up the energy to walk up the stairs  or do simple things. I am not lazy at all I'm super productive usually. I'm very fit as well, not overweight. So confused and frustrated by this. Baby girl has been getting a lot more active lately and I've noticed my appetite has increased. Could she be going thru a growth spurt and it's just wiping me out or could it be something else?
