Yep, I'd say she's a little to close to being ready for something to come out of her to want you trying to put something into her. Poor baby, it does sound like she is soooooo close. Keep her in that pen......do NOT let her get under the bed.......or any furniture. It wouldn't be good for her to start whelping underneath something and not want to come out. Continued good luck to you and the soon to be mama.
