How long does it take for the pregnancy to be completed and she to have cubs?

Their are 3 stages

1. The female is pregnant and she is mich slower just hunt alot of animals and let her eat it

2. The pup is born it cant leave the den so u have to hunt small animals and pick them up and go back to the den to let the pup feed

3. The pup can leave the den but cant hunt i find this stage the easiest as i hunt alot of animals in the area and the pup will just eat

4. The pup can hunt

5. Its all grown up

This took me about 30mins to an hour to complete

It doesn't depend on time, but you have to get 10,000 EXP on that animal to have the baby. The best way to have the baby is to either kill bosses or have the male and/or other pups kill prey and wait for the female to get there.
