Because, women with blood type O will have neonatal hemolysis from the second child, and if they are not dealt with quickly, there will be the possibility of death, which is what you call stillbirth. This belongs to the hemolysis of the ABO blood group system. At present, science believes that according to the doctor's instructions, the fetus is cared for, that is, taking some traditional Chinese medicine or something, can avoid neonatal hemolytic disease, ensure the healthy survival of the fetus, and take medicine has no effect on the fetus.
All you have to do is get pregnant, and then go to a regular hospital for regular check-ups, and if you find that you have hemolytic disease, you may follow the doctor's advice.

Type A or O
Type science research has found that there are three genes that control the ABO blood group in humans: IA, IB, and I.
Among them, IA and IB are dominant to I, and there is no explicit implicit relationship between IA and IB.
That is: the genetic makeup of blood type A can be IAIA or IAI;
The genetic makeup of blood type B can be IBIB or IBI;
The genetic makeup of AB blood is IAIB;
The genetic makeup of type O blood is II.
Usually only two antiserum, anti-A and anti-B, can be used to divide the population into four blood groups.
According to the genetic law of blood group, and for the sake of clinical practice, the blood types of children born between spouses are as follows:
Blood types of children born to various ABO spouses:
The blood type that a marital child may have.
A blood type that a child cannot have.

Type A or Type O.

The child's blood type is a new blood type that is a mixture of part of the father's blood group (A, B, or O) and part of the mother's blood group (A, B, or O), and this new blood type is the child's blood type, so the child's blood type is related to the parent's blood type.
The relationship between the child's blood type and the parent's blood type.
The addition is the father's blood type, the mother's blood type, and the child's blood type.
a+a=a、o
a+b=a、b、ab
a+ab=a、b、ab
a+o=a、o
b+a=a、b、ab
b+b=b、o
b+ab=a、b、ab
