did the seller for that pair actually tell you the female had already laid eggs at some point? the pics arent the best, but she honestly doesnt look gravid to me. try to see if you can get a shot of her angled toward the camera. for someone who just got satanics (which are naturally very slender geckos), a well fed female can look a lot like she's gravid. ill attach a pic of a gravid female.
