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 fertility pills, as specified in the upper section) and forfeits the pregnancy; the smallest has the remaining percentage and leads to success. The spermatozoon with the main character's head indicates where the wheel stops.
Tap the screen or hit the spin button to launch the wheel.
If it lands on the empty and small portion, then the partner will be pregnant. This step may be required for the completion of the route, depending of the character, and the progress of others routes may be paused until this event ends. The pregnancy evolves over 4 weeks until the birth, but 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 during the pregnancy as they are mandatory steps.
