Tired?

Weird question. So, I’m 36+2 and I have a one year old and am continuing to work until baby is here. I just feel like sitting or sleeping all of the time. Obviously I can’t do this with having a little one, cleaning, four pets, and getting my work done. But, I don’t recall being this exhausted with my first.

I can’t remember, is third trimester tiring, or is it just life? I’m worried that I won’t have my energy levels back after pregnancy because currently it’s just life making me tired. Although I expect to be exhausted for the first few months when baby is here.
