While planning to conceive, you may choose natural planning methods such as the ovulation method (intercourse takes place just before or after ovulation) or the symptothermal method (evaluating fertility based on your daily temperature). Remember: women are more likely to become pregnant if intercourse takes place just before or just after ovulation. This is because the unfertilized egg can live for only 12-24 hours in your body. If you have been trying for a few months with no results, don't get discouraged. Only 20% of women who are trying to get pregnant are successful on the first attempt, so don't lose hope or assume something is wrong.
