Hello doctors, let me ask this question. Calculating gestational age based on the date of intercourse and ovulation: If you remember the date of intercourse or have sex on the day of ovulation, you can calculate the fetal age according to that day. There are cases that confirm the date of intercourse and conception, the gestational age will be calculated from that date and added 2 weeks. However, not everyone can accurately calculate their ovulation date. Therefore, this calculation method is not commonly applied. According to the website, the ultrasound is still wrong and usually adds 2 weeks, because when the 4d ultrasound is done, the result is 3.5 months, or about 24.5 weeks, while I remember going to work far away and my husband and I only have sex officially. is 3 months. So in half a month, the other 2 weeks are an extra calculation in medicine or there is a problem of the wrong relationship time. I hope the doctor can help me. Thank you

Hello doctor. Me and her had sex for the first time on February 17 to November 14, when my wife gave birth to a grandchild. So the doctor asked me if such a baby is born early? Because I count 3 more days, it's only 9 months. I don't know if I can conceive for the first time right? Thank you doctor

Hello. Your doctor will rely on the first day of your last period, the level of pregnancy hormone in your blood. However, each person's menstrual cycle is different and the time of conception in each cycle is different for each person, so often calculating gestational age based on the first day of the last menstrual period will be affected and may not be accurate.
Usually doctors will rely on the results of the first trimester ultrasound to have the baby's expected date of birth and the gestational age will not change. On that basis, your doctor has a plan to monitor and care for you and your baby throughout your pregnancy.
Thank you for your question to Vinmec Health System. Best regards.
