Q: What are my chances of getting pregnant via IUI after my basal body temperature (BBT) rise?

A: Your basal body temperature usually goes up the day after ovulation. Your chance getting pregnant are close to zero if you have IUI for the very first time the day after ovulation or later. That's why most doctors like to do IUI the day before or the day of ovulation because doing IUI only the day after ovulation is unlikely to get you pregnant.
