26 weeks and exhausted!

Emily • Married for over 2 years, TTC for over 1 year, 2 previous MMC, expecting my rainbow baby Sept. 2016! 💕
Yesterday, I was full of energy. I cleaned the entire house and cooked all day. Today, I'm finding it difficult to even get out of bed to pee! I'm so sleepy! Is this normal energy loss at this stage? I was hoping I'd feel good until at least 30 weeks.
