Extremely Lazy

So I am 9 weeks and my energy level is literally at 0. After work I come home, eat and go straight to bed. All weekend I only did what was 100% necessary and then came home and got in bed. I’m so excited to be expecting my first little nugget BUT this fatigue/ laziness is starting to concern me. I am usually always out and about. Is this normal? Is it the baby or am I just being extremely lazy?
