I know everyone is different, but after 12 weeks the fatigue starts to wear off and most women start getting their energy back in the second trimester.

I wish that had been the case for me! 2 weeks left, and I've been exhausted since the beginning.

It's absolutely just up to the mom and what she can handle - no one else can decide. If you're tired but feel better being busy, as long as there's no health risk, I say work. I've found that otherwise you spend a lot of time thinking about how you're tired, and it can be discouraging mentally.
