Patient's question:
I'll be 12 weeks tomorrow. During the ultrasound at 80 days of pregnancy, the placenta was measured at 1.5 cm thick, with a function level of 0, and the fetal crown-rump length was 3.5 cm. I've had a miscarriage before, which was very painful, so I'm very worried about this pregnancy.Hello, is the current size of the fetus considered small? It's said that it should be around 5 cm to be considered normal. If it is small, what should I do? Could it be a sign of another miscarriage? Besides what people say—that as long as the placenta develops, one can feel slightly relieved—is that correct? Please provide a detailed explanation. Thank you!!!!
Doctor's answer:
The fetal head circumference is 3.5, which is consistent with a gestational age of over 70 days and lower than the time you mentioned. There are two possible reasons for the smaller size: one is a delayed conception, and the other is poor growth and development. Embryonic arrest is more likely to occur during early pregnancy, with an increased risk after the third month of pregnancy, but it can also happen again. In your case, it is important to rest and consider taking pregnancy preservation medication for preventive use. I hope the above information helps you. Thank you.
