it's just me or is that hard to make her pregnant? tired for weeks and weeks to get a ending and still didn't manage to succeed.
You can adjust the chance of pregnancy in the settings and (very handy) choose to make the screen flash a pink colour when Tomie gets pregnant after sex. It's also possible to buy ovulation-inducing pills so you don't have to wait a week for Tomie to ovulate again.
Home screen --> content options --> pregnancy and menstruation. Then choose these:
Chances of getting pregnant from vaginal sex while ovulating: 30% (max)
Contents related pregnancy: On (obviously)
Pink flash effect at the moment of pregnancy: On. If Tomie becomes pregnant after vaginal sex, a pink flash effect will appear. Afterwards, just skip ahead by choosing the 'call someone' option and call Mari for example, after which the day ends. Keep skipping ahead until Sunday, which is iirc the day that Tomie does a pregnancy test.
When starting a new game, you can also choose the 'dangerous ovulation' trait, which doubles the chances of getting pregnant. You need 2 trait points for this (so it can only be 'bought' after reaching 2 endings).
If you're not sure whether Tomie got pregnant, then there are 2 hints from which you can deduce that Tomie is pregnant:
1. If you choose not to use a morning-after pill, Tomie will say that she feels a little nauseous.
2. If you choose to use an ovulation-inducing pill after Tomie (presumably) got pregnant, then a system error will occur, which says that the pill can't be used at this time.
Also, when Tomie ovulates, some dudes will notice that (idk how) and try a *little* harder to make her pregnant, so there are some rare scenes that can occur then.
