How long does it take for the fetus to spontaneously abort?

Fetal growth retardation will lead to spontaneous abortion in about one month, and the specific time is mainly determined by changes in hormone levels in the body.

How long does it take for the fetus to stop growing before it can lead to a spontaneous abortion?

Fetal growth retardation refers to the cessation of development or death of an embryo in the uterus. Since the levels of estrogen and progesterone in women's bodies remain high after fetal growth retardation, it is possible that the arrested embryo will remain in the female body for a period of time. As the estrogen and progesterone levels in the female body gradually return to normal, most arrested embryos will be expelled from the body on their own. This process takes about one month. After fetal growth retardation, the embryo stays in the uterine cavity for too long, which can easily cause abnormal coagulation function. Therefore, it is recommended that if there is no sign of the embryo being expelled on its own one week after the discovery of fetal growth retardation, you should go to the hospital in time for treatment, and the doctor will use exogenous intervention to promote the expulsion of the embryo to prevent the embryo from being retained in the body for a long time and causing damage to the health of women.

Things to note after abortion:

Sexual intercourse should be avoided within one month after fetal growth retardation to avoid affecting the recovery of the female uterus and ovaries. In the short term, bed rest should be taken to avoid overwork and heavy physical labor to prevent poor recovery and avoid affecting the later pregnancy.
