Frequently Asked Questions (FAQ)

Q1: How accurate is the due date provided by the calculator?

A1: Our calculator uses medically-established formulas to provide an estimated due date. However, it’s important to remember that only about 5% of babies are born on their exact due date. Most babies are born within a window of about two weeks before or after the estimated due date.

Q2: Can I use this calculator if I have irregular periods?

A2: Yes, you can. If you have irregular periods, it’s best to use the conception date or IVF transfer date option if you know it. If you’re unsure, use your best estimate for the LMP and consult with your healthcare provider for a more accurate dating.

Q3: How does the calculator account for leap years?

A3: Our calculator automatically adjusts for leap years in its calculations, ensuring accuracy regardless of whether your pregnancy spans a leap year or not.

Q4: Can I use this calculator if I’m pregnant with multiples?

A4: While the calculator can provide an estimated due date for multiple pregnancies, it’s important to note that twins and other multiples often arrive earlier than single babies. For the most accurate information, consult with your healthcare provider.

Q5: What if my cycle length varies from month to month?

A5: If your cycle length varies, use an average of your cycle lengths over the past few months. For the most accurate results, it’s best to consult with your healthcare provider who can take into account your specific menstrual history.

Q6: How often should I use this calculator during my pregnancy?

A6: You typically only need to use the calculator once at the beginning of your pregnancy to get your estimated due date and initial timeline. However, you can refer back to it throughout your pregnancy to check on fetal development milestones and your current gestational age.

Q7: Can this calculator predict my baby’s gender?

A7: No, this calculator cannot predict your baby’s gender. Gender determination typically requires medical tests such as genetic testing or ultrasound imaging.

Q8: Is this calculator a substitute for prenatal care?

A8: Absolutely not. While our calculator provides valuable information, it is not a substitute for professional medical care. Regular prenatal check-ups with your healthcare provider are essential for monitoring your health and your baby’s development throughout pregnancy.

Q9: How does the calculator determine fetal development milestones?

A9: The fetal development milestones provided are based on average developmental timelines established through medical research. However, every baby develops at its own pace, and your healthcare provider can give you the most accurate information about your baby’s specific development.

Q10: Can I use this calculator if I’m not sure about my LMP date?

A10: If you’re unsure about your LMP date, it’s best to use your best estimate and then confirm with your healthcare provider. They may recommend an early dating ultrasound to get a more accurate gestational age and due date.
