The absence of buds until about 8 weeks of pregnancy is usually normal and does not require treatment. No buds after 8 weeks of pregnancy may be due to fetal abruption, which usually requires termination of pregnancy. The first reason for the lack of buds in a woman’s pregnancy may be that the pregnancy is short and the buds have not yet grown. In most cases, the buds can be seen by ultrasound at around 7-8 weeks of pregnancy. If the menstrual cycle is long, the fertilized egg is fertilized late, or the gestation period is short, there may be no buds at the time of checkup, which is a normal phenomenon. If the HCG doubling is normal and the embryo keeps growing through ultrasound, it can be observed temporarily and rechecked every few days to see if the fetal buds have grown out, and no special treatment is needed. In another case, if the pregnancy lasts more than 8 weeks, but there are still no buds, and the HCG doubling is not good, it means that the embryo may have stopped developing. There is no treatment after the embryo stops developing, you can only go to the hospital to terminate the pregnancy in time, and check the cause of the fetal arrest and then treat it.
