So tired

I’m 35 weeks 2 days pregnant and I CANNOT stay awake. It’s insane. I’m so fatigued and exhausted alllll the time. It makes me feel so guilty like I’m gonna hurt the baby by being so tired and sleeping so much, I feel like I should be up moving around and being healthier. Is this normal? At 28 weeks when my blood was drawn for the glucose testing they also said my anemia draw came back good, so that means my iron should be ok right? I thought iron and anemia were related but maybe not?

Let me know
