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 most accurate gestational age can be determined from early pregnancy ultrasound results, which can also roughly estimate the time of intercourse for conception. The ultrasound examination on August 8 indicated a gestational age of around 10 weeks, suggesting a high possibility of conception occurring in early June.
