My fiance's father just died and I'm pregnant. His mother wouldn't let me hit the child or get married early, so she went to divination and set a date.

Let's understand each other. After all, my father died, and according to ancient times, I still have to be filial for three years. It won't be needed now, but it will take a hundred days. Just finished the white one and made the red one. I can't accept it in my heart. My grandfather died, and my wedding date has been postponed for four months. As for your present situation, it is really quite special and wronged. It depends on your own ideas. If his mother is good to you at ordinary times, it's okay to put it off until September. If you feel uncomfortable, you can register first. But if I don't like you at ordinary times, that's debatable.
