I am 22 weeks ATM and wondering if I am overdoing it or not?

We have just moved into a new place and I have been doing a lot of unpacking etc in the past two weeks, I have also just moved areas from relatively desk bound job to one that requires me to walk and be on my feet for the majority of the day.

Put house work and general domestic duties on top of that and some days I feel like I may be overdoing it.
How do you know?
