Careful with when the timer is enabled. Menus and dialogue, it should be disabled, along with cutscenes. If you have any of those, you can add a line of code for timer temporarily disable.
either shut it off at the event start, and on “after” the event ends.
Or just temporarily halt timer progress while it is one of those event.
Its better to be able to pick and choose for ease of use. You might add a cutscene for failure that has dialogue but also where the pregnancy meter is still active.
