I know how you feel. I am looking now at ways to lessen the load without being conspicuous. I bowed out of my first thing this week--a thing at our mosque. I made sure there was coverage for the event, and then didn't show up.
I am thinking about buying bread instead of having to bake for a while.
In my case, my workload is big because of the gap before me...I am still playing ketchup 6 months in. And I have a trade show coming up this weekend (I don't go, but I order all the materials, coordinate the exhibit, etc etc), so it's been heavy the past few weeks. And now I am newly pg--sick AND tired.
I want so badly to tell the boss I am pg, but it is too early for me to be comfortable. He is a friend first and a boss second, but still. He was totally understanding and excellent when I was out with my ectopic, just weeks after I started. But I don't know.
My house is a mess, my ds needs a bath, and I am NOT at all motivated to actually work!
