this happened to my female bearded dragon a few years ago. we were new to breeding and didnt know what the hell to do either. we contacted our local pet shop we knew very well and got her to an ER vet. they were able to put it back inside her and put 2 stitches in her too. she was fine in the end and even bred again many times with no problems.
sometimes it will go back inside by itself, but not all the time. i would get her to a vet asap. better safe than sorry. just keep it moist and away from anything that would get it dirty.
