Depends: This depends on whether your cycles are very regular. As a guideline, if your cycles are 28-30 days, you would ovulate on or about Nov 14 to 16. The egg lasts about one day and sperm can survive 3to 5 days. Conception could occur somewhere around Nov 9 to 17. This is only a guideline and your obstetrician can better advise you and you should review these dates with him/her.
