Everything for me has always been "normal" before birth in that department. With my first birth, I awoke with a "different kind of contraction." I had some bloody show within a few minutes, went downstairs to call my mw & had a good sized bm. That was it - I cleared out.
With Dd2, I again awoke in the middle of the night to a contraction & had bloody show again within a few minutes. I kept waiting & waiting for the big bm, "the signal."
The pressure ended up becoming so intense that I was holding my crotch from front to back. I kept visiting the pot thinking that the big bm was coming! Never came, but my water blew like a geyser! And away went all of the pressure

, never did poop with Dd2...
