It's usually a good thing! The less a female lays eggs the less strain it will put on her body and the longer she could end up living. Especially if she's primarily a pet.
That being said, does she have access to a laying bin in her cage in case she ever does need to? The first time can always be tricky to spot, especially if maybe you've never had females before. Especially if they have a low number of eggs she may not get as bloated as a female carrying 50 eggs, for example. So telling by physical condition alone might be harder. Additionally, keep good records of her weight. Weigh her once a week if you can and write it down, so you can track when she seems to be gaining a lot of weight quickly vs. when she is holding fairly stable.
And of course, you can always share photos with us if you're ever in doubt and we'll see if she looks gravid or not.
