I found the best way to poop now that Charlie's lovely little head appears to be blocking the exit. I get into the child pose from Yoga but stick my butt up in the air. A few minutes is all it takes to relieve enough of the pressure to get some relief. I've been doing it nightly if I don't otherwise go. It's not ideal, but it's better than nothing!

Re: Mierda (shit in Spanish this week!)
It's gotten to the point where DH will ask if I've pooped today, and give a a little "yay!" When I say yes.
Edit because my thumb got post happy before I was done typing
