Is this normal?

Its completely normal to be exhausted at 38 weeks right? I'm finally done with working and feel like I can just relax now! Before pregnancy I alwaysss loved taking naps. Well now that i am 38 weeks i take like 2 naps a day.(about 2 hours each) i am not sleeping well at night. I am dealing with carpal tunnel and being uncomfortable. I wake up what seems like every hour to switch to laying on my other side. Well my mom seems to be worried that I am this tired. She is constantly asking if im okay after i tell her i am taking a nap. ( i know she is just worried about me,but let me sleeep!😂)

I keep telling her that I think its normal to be tired when 9 months pregnant on top of not sleeping well at night. I mean this is when i should be getting in as much sleep as possible right? Before the baby is here!
