Exhausted

I am almost in my third trimester (literally days). This whole pregnancy My only symptom has been fatigue (I’ve been so lucky). However, starting last week I just feel the fatigue x100. I’m a ftm and I’m wondering if this level of fatigue is normal? Like is it just pregnancy fatigue? Am I fighting some kind of virus? I just am wondering if any other mammas have experienced this? Is it normal?

I know fatigue is norma but like is it normal to feel so fatigued that you’re like fuck I can hardly function?
