Want to know the conception date

Patient's question:

Patient Gender: Female
Patient Age: 28
Want to know the conception date

Doctor's answer:

Generally, gestational age and estimated due date are calculated based on the last menstrual period, but the gestational age calculated from early pregnancy ultrasound results is the most accurate, and it can also roughly estimate the time of conception. The ultrasound examination on August 8th indicated a gestational age of around 10 weeks, suggesting that the likelihood of conception occurring in early June is high.
