How do you increase your chances of getting pregnant at home?

Every other day: Have sex every other day during days 9-16 of your ovulatory period. That is, 9 days after you started (not after you ended) your last period. Decreasing stress, getting enough sleep, having a normal weight, regular exercise and a healthy diet will also contribute. 48 years of age, however, is late in a woman's reproductive cycle to conceive naturally.
