Yeah before the ending if you do the "Fingering" sex scene, like, it's pretty obvious considering she keeps mentioning it's not a safe day and all.
Do you know the specific way of triggering the pregnancy? Is it a scene that you cannot repeat?
Because in that case it means I may have to play the entirety of book 3 again and take every single chance to creampie Toph.
With Katara you only do the scene I mentioned. The only scene with Toph the dialog only mentions the possibility of having her stop taking birth control.
