Pregnancy

Has anyone heard that in order to up your chances of conceiving to have intercourse every other day for the 2 weeks leading up to your AF? I came off if birth control 2 months ago last months cycle was 32 days and this months was 28 days. My husband and I were trying to conceive around the 18th day of my cycle when we probably should have been trying around the 14th day. BUMMER.
