What happens if I have a miscarriage at four months of pregnancy?

Spontaneous miscarriage is very scary for pregnant women, but in life there are still many pregnant women who experience spontaneous miscarriage.

What happens if I have bleeding and miscarriage at 4 months of pregnancy?

1. Genetic defects

If there is a chromosomal mutation in the expectant mother or father, it will be passed on to the baby, and gene mutation becomes the main culprit of spontaneous abortion. The most obvious is miscarriage within the first 3 months, half of which is caused by chromosomal abnormalities in the embryo.

2. Blood type incompatibility

If the expectant mother has ever received a blood transfusion, or if coagulant factors that are incompatible with her blood type are produced during pregnancy, the fetus will cause agglutination and hemolysis, resulting in miscarriage.

3. Uterine malformation

If the expectant mother has uterine malformations, such as bicornuate uterus, uterine septate and uterine hypoplasia, it will affect the implantation and development of the embryo and lead to miscarriage. Relaxation of the internal os of the uterus or deep laceration of the cervix can cause premature rupture of membranes and late miscarriage.

4. Systemic diseases

If an expectant mother suffers from an acute infectious disease such as influenza, typhoid fever, pneumonia, etc., bacterial toxins or viruses, such as herpes simplex virus and cytomegalovirus, may enter the fetus through the placenta, causing the fetus to stop developing and leading to miscarriage.

What are the symptoms of spontaneous abortion?

1. Vaginal bleeding

Vaginal bleeding during pregnancy is abnormal and should be treated with caution. According to statistics, if vaginal bleeding occurs in the early stages of pregnancy, about half of pregnant women can continue to be pregnant successfully, while about 30% of pregnant women will experience spontaneous abortion.

2. Abdominal cramps

Usually mild abdominal pain can be treated by resting in bed, but if the abdominal pain is severe or accompanied by symptoms such as vaginal bleeding, you should seek medical attention as soon as possible.

3. Uterine contractions

Pregnant women in the second and third trimesters should pay special attention if they feel that the frequency of uterine contractions is becoming more and more frequent, or even reach a regular contraction every ten or twenty minutes, or the contractions are frequent, or they feel pain during contractions.

4. Backache and abdominal distension

If a pregnant woman feels pain in the waist, a heavy feeling in the abdomen or other abnormal symptoms, she should seek medical attention if the condition persists.

5. Early rupture of membranes

When a pregnant woman experiences symptoms of premature birth such as ruptured amniotic membrane, leakage of amniotic fluid, dilated cervix, continuous contraction of the uterus and bleeding, she should seek medical attention as soon as possible.

The above is an introduction to what causes bleeding and spontaneous abortion in the 4th month of pregnancy.
