Anyone drop yet?

Tao • 26. Engaged. 7 year old girl and due September 2016. 2 Weimaraner kids.
I feel as though my belly has dropped! I have a waddle and it just feels heavy now. I am 29w2d. I feel like I have more room under my breasts when standing. 
Everything is getting increasingly more uncomfortable like sleeping and getting up from sitting. 
What's happening with all your bellies so far?
