Hi Taylor;

Danios are egglayers so they really don't get "pregnant". It probably does have eggs though. But, the tank may be too crowded for her to spawn, the water chemistry and temperature isn't right, or the male is just not interested in breeding. There should be a certain temperature change and plenty of room for them to spawn in a separate spawning tank. Here is more info on keeping and breeding danios, just scroll down to the section on zebras;
