How real is nesting? 🍼

KC • Mama to an 18mon old little lady and baby boy is due May 9, '18❤️
For those of you who have had children already, did you get a burst of energy close to when you gave birth? 
Just curious, as I am 37w3d and I have had far more energy in the last 4-5days than I have had throughout my whole pregnancy. People keep telling me it might be a sign that she is coming soon.
