Pregnancy is the most metabolically demanding thing your body will ever do. Your blood volume goes up about 50%. Your heart grows 30%. Your kidneys filter 50% more blood. You build an entire new organ from scratch (the placenta), and that organ produces more hormones in a day than your body usually makes in months. You grow another person's bones out of your own minerals.
If you're pregnant and your body wants to rest instead of working, cooking, or showing up somewhere, listen to it. There's no other state in your life where your body is doing this much underneath.
