Grab a newspaper and a cup of coffee. Relax. Enjoy being able to poo like in the old days!
As what's left of your colon cleans itself out, these movements will become less common. Then after a month it's like, YAY! and you pass a little mucus poo. And then after that, monthly or so. Enough to grab something to read and take your time and remember the old Daily Days. . .
There was a part of me, after surgery including a colostomy, pooing out of my butt and thinking, "maybe they got it wrong! maybe I'm really OK and I can poo normally after all." A beautiful moment of denial on the potty. 5 minutes of joy. In some ways, it was almost worth having a colostomy to experience the joy of that 5 minutes: "you don't know what you've got 'til it's gone" So. . . when it's gone, and you understand what you HAD, it's kind of a neat place to be. . .
