Walking My Life Away

Kirby • 22. Can't wait for my baby boy to get here! Hurry up August!
I'm 38.2 wks pregnant and absolutely miserable! I got checked by my dr this week and I'm only half a cm dilated! Baby was already 7lbs 3oz at my 36 wk appointment and already head down! I thought for sure he would be here by now! Well yesterday I waked two miles and today I feel like baby isn't as active. Is this normal?
