Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How can I calculate gestational age using the biparietal diameter?Doctor's answer:
The formula for calculating fetal weight based on biparietal diameter is: fetal weight = biparietal diameter (cm) multiplied by 900 minus 5200. Due to individual differences among expectant mothers, there will inevitably be some error in the fetal weight calculated from ultrasound data. Expectant mothers should only use it as a reference.In your case, you should go to the hospital for a check-up. Generally, it is recommended to have the intrauterine device (IUD) inserted three days after the menstrual period is clean. Strengthen your nutrition, get adequate rest, and supplement with vitamins and trace elements.
