When you succeed in the minigame, the progress of some routes are paused until this event ends. The pregnancy evolves over 4 weeks until the birth. You have to wait another 2 weeks until the baby is sent to daycare and you can resume normal activities. Don't forget to read the phone messages as they are mandatory steps.
You can increase the success on pregnancy with fertility pills. They are given by Dr. Priya Singh at the clinic and they raise the chance of pregnancy from 20% to 40%.
How to play
The pregnancy minigame is a roulette-style wheel mechanism with 2 spaces: the largest one represents 80% of the wheel (or 60% if you took the pills, see upper) and forfeits the pregnancy; the smallest is the remaining percentage and leads to success.
