At 20 weeks of pregnancy, how big should the fetal head and neck be?

Patient's question:

I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting my fertility, and I'm also extremely sensitive to cold and coldness. Could you please tell me what the head and neck size of a 20-week fetus should be?

Doctor's answer:

Hello, at 20 weeks of pregnancy: The average biparietal diameter is about 4.88 ± 0.58 cm. You can compare this with your own measurement. Pay attention to regular prenatal check-ups. The occurrence of gynecological diseases not only affects a woman's life but can also lead to the development of gynecological diseases. Therefore, it is best to have a vaginal examination in the gynecology department of the hospital to identify the cause and treat accordingly. Pay attention to personal hygiene and keep the perineal skin clean.
