The results from BumpDate's calculators are estimates for general planning only. They are not medical advice, and they are not a diagnosis or a substitute for the care of a qualified healthcare professional.

Due dates are estimates. Only about 4% of babies arrive exactly on the due date, and your provider may adjust the date after an early ultrasound, which is the most accurate way to date a pregnancy. Do not make medical decisions based solely on this site.

These tools cannot detect pregnancy complications. They do not replace routine scans, bloodwork, or the judgment of your care team. If something feels wrong — reduced fetal movement, pain, bleeding, or any symptom that worries you — contact your doctor, midwife, or local emergency services right away rather than checking a calculator. If your pregnancy is high-risk, follow your provider's personalized schedule rather than the general timelines shown here.

BumpDate is not responsible for any action or inaction taken based on its content. The site is a planning aid, not a monitoring device, and it should never be used to decide whether to seek care.

Using this site does not create a patient–provider relationship. For personalized guidance about your pregnancy, always confirm dates, milestones, and care plans with your own provider.
