Natural Cycles gives women the skills they need to track and get to know their unique cycles better so that when the woman is due to ovulate, the couple can time intercourse and maximize their chances of conceiving.
There are 2-3 days per cycle when a woman has the highest chances of conceiving, which is around ovulation day, while the fertile window is at six days in total. Ovulation day is the phase of the menstrual cycle when an egg (oocyte) is released from the ovaries and can be fertilized by sperm. By analyzing a woman's basal body temperature and LH levels, the Natural Cycles algorithm can find ovulation day and the days when you are the most likely to get pregnant to increase your chances of conception.
Fertility is a continuum, which means everyone’s chances are different and many factors can influence your chances at any given time.
