Could be gravid but IMO probably not. My females when gravid typically show as larger in diameter but only about the middle third where the babies are. Your pics look to me like a nice well fed good body weight female. Maybe she is gravid but early on and/or small litter size? Only time will tell. Is she eating? If not, could be a good indicator of being gravid.
Here are a couple of pics of gravid females:
