Spontaneous abortion

Termination of pregnancy if the pregnancy is less than 28 weeks and the fetal weight is less than 1000g is called spontaneous abortion. Spontaneous abortion can be divided into early spontaneous abortion, intermediate abortion and premature abortion according to the time of occurrence. Spontaneous abortion in the first trimester Often, spontaneous abortion refers to flowing out of the mother's body before the fetus can survive. Spontaneous abortion accounts for about 15 to 30 percent of all pregnancies. A miscarriage in the first trimester of pregnancy is called spontaneous abortion in early pregnancy. A miscarriage between the 12th and 20th week of pregnancy is called intermediate abortion. A miscarriage after the 20th week of pregnancy is called premature birth. The fetus is likely to survive but requires very advanced nursing conditions.
