are u handling her after she sheds. they almost always go right after they shed. the last two were pee. not poop. if ur holding her and shes really moving around and trying to get away then she is scared or stressed. and that is prolly why. once she starts really moving and trying to get away put her back. also look at her vent. if she is really big and looks like she has something ready to come out dont take her out. and her crawling around only helps her get that poo and everything ready to come out
