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 can only use it as a reference. For your situation, you need to go to the hospital for a check-up. Generally, it is recommended to have an IUD inserted three days after the menstrual period is clean. Strengthen nutrition, pay attention to rest, and supplement vitamins and trace elements.
