For couples planning pregnancy, timing intercourse during the 5-day fertile window preceding ovulation maximizes natural conception odds. Ovulation typically occurs 14 days prior to the start of the next menstrual period.
Formula & Clinical Methodology
Determined via clinical luteal phase estimation. Ovulation Day = Next Period Date minus 14 days (luteal phase). The fertile window spans 5 days prior to ovulation through 1 day post-ovulation, with peak fertility occurring 1-2 days before egg release.
