Do you have a high chance of pregnancy at age 24 having intercourse the day of ovulation, the day after ovulation, and the 3 days before ovulation? had a positive ovulation test is how i knew i was ovulating

Conception & PG: Ovulation timing is only one of many factors that allow conception. The presence of normal sperm at the right place, in adequate numbers, and the right time also are factors. Ovulation tests can be inaccurate as they turn positive AFTER the egg is already released and sperm need to be present in the Fallopian tube prior to or immediately after that time.
