Sooo tired!

Melissa • My husband and I were blessed on November 19 2015 with our son Nolan! Currently pregnant with baby #2 👨‍👩‍👧‍👦
I'm 20 weeks 3 days and for the past couple of days I have had no energy all day long. I just feel like I could literally close my eyes and fall asleep at any point during the day.. Is this happening to anyone? I've had a lot more energy every since being in my second trimester.. (Up until now that is)
