Frequently Asked Questions
What is the "Fertile Window"?
The fertile window is the period in a woman's menstrual cycle when pregnancy is possible. It typically lasts about 6 days, including the day of ovulation and the 5 days preceding it.
How accurate is this tool?
Our calculator uses medical-grade logic based on average cycle lengths. However, since every woman's body is unique, we recommend using this as a guide alongside other methods like basal body temperature or LH testing.
