The absence of fetal heartbeat and fetal buds at 55 days of pregnancy can lead to cessation of development. The absence of fetal heartbeat and germination can be caused by chromosomal abnormalities and abnormal fetal development. In this case, the first thing that is recommended is to terminate the pregnancy. If you have a period once every two or three months, you can observe it for another week, because it is normal as long as it occurs within 60 days. However, if each period is very normal and not delayed or advanced, it is recommended to terminate the pregnancy as soon as possible to avoid prolonged embryo in the uterine cavity, which may affect the health of the body and may also cause intrauterine infection. Therefore, an active abortion should be performed, which can help to bring the uterus back to normal quickly, so as to avoid long time residual in the uterine cavity, which can cause damage to the body.
