This tool allows women to estimate the days in their menstrual cycle when conception is most likely. Inputting information such as the first day of the last period and average cycle length enables the calculation of a fertile window. For example, a woman with a 28-day cycle might find her fertile days are approximately between days 11 and 16.
Determining this timeframe can be valuable for family planning. For those trying to conceive, identifying the most fertile days can increase the chances of pregnancy. Conversely, those wishing to avoid pregnancy can use this information to take precautions during this window. Historically, women have tracked their cycles, and contemporary methods offer more precision.
