Menses regular?: How regular your menstrual cycles are will influence this answer. It would be unlikely for you to conceive as early as cycle day 5 (April 30th). Typically a woman with regular 28-30 day cycles will ovulate on cycle day 12-14. The second intercourse event of that month occurred on cycle day 18 so it is possible that you could conceive on that day, especially if your cycles tend to be longer.
