Tired

Maybe it’s all coincidence, but almost immediately after beginning the third trimester, I have been exhausted again. The last two days I’ve been really tired at work, especially at the end of the day, and I’ve taken naps when I've gotten home. I have zero energy to work out. Last night I napped from 6 until 9 p.m., woke up to eat and watched TV for an hour or so, and was in bed again by 10:30 and slept until 7 a.m. Normal? I have no idea. All I know is that I’m tiiiiiiired. And my back hurts. Nate thinks I should get a massage. I think I’ll let myself get talked into it.
