Guideline: If your cycles are quite regular at 28 to 30 days, you would have ovulated on sept 15 or 16. The egg lasts about one day and sperm can survive up to 5 days. Therefore unprotected sex on 9/21 would be unlikely to result in conception as the egg shouldn't be viable after 9/18 Of course this is a guideline and assumes very predictable cycles.
