Can you steal Judy's birth pills yet? Im idk how

Just continue in her storyline to a point where you ask her "I wanna have a baby with you" and from that moment she can get pregnant. Taking the pills earlier would lead to a story point where she is still with Mathew and that would deserve separate storyline, for which we will make vote in the future.
