Give her a warm bath, and while she is in the bath, or right after, massage her belly. DO NOT ever hold any lizard upside down. They can not breathe, and it crushes their organs. Leave them upside down for any period of time, and they WILL die. Just find a comfortable way to be able to get your finger up under her and gently rub towards the vent. What are you using for food? Mealworms are notorious for impacting dragons (where they won't poop), and of course pet stores sell them to you for dragons. Also, put some mineral oil on her food about 5 times a week until she passes whatever is impacting her, then promptly gether off of it. (Is she eating mealworms? is she on sand? etc.).. The mineral oil should end up about 1-2 drops every day you use it.
