A 47-day pregnancy with buds but no fetal heartbeat is usually normal, as the pregnancy is relatively short and the fetal heartbeat cannot be seen for the time being. Generally, the pregnancy sac can be seen in the uterine cavity through ultrasound examination around 42 days of pregnancy, and some women have ectopic pregnancy, so the pregnancy sac cannot be seen in the uterine cavity. Generally speaking, the buds can be seen on the 40th to 50th day of pregnancy, and the heart of the fetus can be seen on the 50th to 60th day of pregnancy. It is normal that the heart of the fetus cannot be seen on the 47th day of pregnancy, and it can be observed for the time being. Some women are late for the fertilization of the egg and the appearance of the fetal heart is also late, you can delay the examination for one week on top of 60 days to make sure that there are fetal buds and the development of the fetal heart, which proves that there is a live fetus in the uterus, and only then can you continue to conceive. If you are pregnant and have buds but have not been able to see the fetal heart, you should be alert to empty sac pregnancy, which may be caused by chromosomal abnormality of the embryo, poor quality of the embryo and other reasons. Do your pregnancy checkups well so that any abnormalities can be dealt with in time.
