How is the specific day of conception calculated

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 way to determine gestational age is through an early pregnancy ultrasound result, 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 likelihood of conception occurring in early June. The occurrence of gynecological diseases not only affects a woman's body but can also lead to the development of gynecological conditions. Therefore, it is best to visit the gynecology department of a hospital for a gynecological examination. After identifying the cause, symptomatic treatment should be administered. Additionally, it is important to pay attention to personal hygiene and maintain cleanliness in the perineal area.
