When's the best time to conceive?

The best time to conceive is during the “fertile window” – that is, during the 6-day interval ending on the day of ovulation.1

If the need to ‘schedule’ intercourse on a particular day or hour adds stress, simply increase the frequency of intercourse beginning soon after menstruation ends if the female partner is having regular menstrual cycles.

If your cycle is irregular or shorter than 21 days or longer than 35 days, ask your doctor for help with determining your fertile phase.
