Mice pregnancy generally does not show until the mouse is fifteen days pregnant. The mouse gestation period is twentyone days long. At day fifteen your mouse will be quite large and her stomach will be very visible. Before the fifteen day mark it is very hard to tell if the mouse is pregnant. I would suggest weighing it every day to see if is getting any heavier. To do this you will need a scale that weighs things in grams or ounces. If you do not want to weigh your mouse I would wait a few days and see what it looks like. If your mouse has not given birth in three weeks, than it is not pregnant.
I think they have a white bit don't know x
She will not run the well she will not go out of her nest
you can tell if a roley poley is a girl from a boy because if the girl is pregnant shes white with less grey

Not exactly, a lot of people may tell you that the gestation period for a mouse is between 18-23 days but my mouse turned out to be pregnant when we bought her and she had her babies at 6 weeks!
if it looks fatter
I think when they are pregnant their tummies turn white.
If There Is Lumps On The Female's Side :)
It is like if a hamster is pregnant after about 10 days your mouse will be much fatter and much more active.AnswerA pregnant mouse in the last week before she delivers will be visibly large starting from her waist area all the way to her backside. In fact, most expectant mouse mothers-to-be will be pear-shaped. these i am sure you know but I'll tell you anyway when a mouse is getting pregnant she will eat a lot more than she does normally and get fatter her belly will be like a round circle. hope it helps :)
