If this is your first poop, then it would be a good idea to bag it up and have a fecal done by your vet. If your husbandry is up to par, then I would not worry about where she prefers to chill out after going. I prefer using newspaper for substrate and I replace and clean the entire enclosure after they go. In your case, you should be fine by spot cleaning the area(poop/pee). I'm sure someone who uses aspen and the likes will chip in.
