Can't do what I used to

I'm feeling frustrated. I can't do all the things in a day that I used to. For example I used to be able to weed the entire garden in one day, now I need 2-3 days to get it all done. Of course I don't think I was this diligent last year since I didn't know what I was doing.

Another example, after cleaning the house, I need to lay down. I feel frustrated because we are just at the halfway point of this pregnancy and if I'm already needing to slow down, what am I going to be like at the end?

I suppose it's a good thing that I can listen to my body and know, but it also makes me really wonder how some women don't know that they're pregnant.

Other than that frustration everything is good as gravy :)
