exhausted?

Brittain • Wife to an amazing husband & Mama to a beautiful boy!
Okay so I'm 22 weeks and these past 2 days I just have had no energy. I woke up this morning at 5:45 with my husband and by 9:20 I was so tired I took an hour nap. Woke up and felt like I could still sleep. My question is, is this normal??? I know the second trimester you're supposed to have all this energy but I don't want to be sleeping too much? If ya get me
