During the pregnancy check-up, more than one ultrasound examination will be performed. B-ultrasound examination can clearly see the stage of fetal growth and development in the abdomen, thus determining whether the fetal development is in line with gestational age. If the gestational age has reached a certain stage and the fetal heart or embryo cannot be seen, further medical examination or intervention is needed. Can we see fetal heart and fetal sprouts in 46 days?
In early pregnancy examinations, there are two indicators that can reflect the development status of the fetus, which are fetal heart rate and fetal bud. As expectant fathers and expectant mothers, they are particularly excited when they hear about fetal heart rate or see fetal sprouts for the first time. So what are fetal sprouts and fetal heart? After the egg and sperm meet and combine, they form a fertilized egg. The first two weeks of fertilized egg development are called fertilized eggs, and after the formation of fertilized eggs, various organs of the body begin to develop. Then it goes through the stages of gestational sac, fetal bud, and fetal heart, and finally forms the fetus.
Generally, after thirty days of pregnancy, cells begin to differentiate and then form fetal buds, which continue to develop into the fetal heart. As the embryo develops, a gestational sac is formed at 30 to 40 days, a fetal bud is formed at 40 to 50 days, and a fetal heart is formed at 50 to 60 days. Therefore, if you go for an ultrasound at 46 days, you can see the fetal buds. But in general, the fetal heart rate is not invisible.
