Q: When should I have sex based on the rise in my basal body temperature?
A: Your typical rise in temperature usually happens one to two days after ovulation. If you have sex after ovulation it is very unlikely for you to become pregnant. If you do not want to get pregnant, then you should have sex only after the typical rise in temperature, but if you want to get pregnant, then you should have sex well before ovulation, several days before the temperature goes up.
