I noticed a huge difference in Carter's bowel movements after we started solids! He used to only go every 10 days or more before solids (exclusively breastfed) and after it was 2-3 times a day! It would also depend on what exactly he ate! If he had oatmeal, peas, beans or any other high fibre food it was definitely worse than if he had something like a banana.
Was your lo's movements like diarrhea or was it a normal poop? If it was abnormal then I would be inclined to think that the food wasn't sitting right with her.
