At the latest how many days there are fetal heart buds

If a woman's menstrual cycle is regular, the fetal bud can be seen when menstruation stops for 5 weeks, the primitive cardiac pulsation can be seen when menstruation stops for 6 - 7 weeks, and some pregnant women will see the primitive cardiac pulsation when they are 8 weeks pregnant. At this time, the baby is still an embryo, and the body tissues and organs are already developing. Pregnant women should actively go to regular hospitals for ultrasound examination to understand the development of the fetus. If the embryo bud and fetal heart are not seen for a long time, it is likely to show fetal arrest. More consideration should be given to factors related to poor embryo quality and insufficient maternal hormones. It is necessary to combine human chorionic gonadotropin examination and progesterone value examination to comprehensively judge the development of the embryo. If necessary, it is necessary to terminate the pregnancy in time.
