At which phase of menstural cycle pregnancy is most likely to occur?

The correct answer is Ovulatory Phase

During the ovulatory phase, a mature egg is released from one of the ovaries. This phase typically occurs around day 14 of a 28-day menstrual cycle, but it can vary from woman to woman. Pregnancy is most likely to occur if fertilization of the egg by a sperm cell happens during the ovulatory phase.
