Causes Of Miscarriage
There are many causes, but the causes are often unknown. About a quarter of miscarriage occur in the first 3 months of pregnancy, the cause is usually due to fetal problems. If there is a miscarriage in the second trimester of pregnancy (weeks 14 to 26) it may be due to the health condition of a pregnant woman. Late miscarriage can be caused by infection around the fetus, leading to early rupture of membranes before abdominal pain or vaginal bleeding. In rare cases, miscarriage due to cervix opening too early.
Miscarriage in the first 3 months
Most miscarriage in the first 3 months is due to fetal chromosomal abnormalities.
Chromosomes are blocks of DNA that contain genetic information that regulates most body problems, from the development of cells in the body to the color of a child's eye color.
Sometimes, there are some errors at the time of fertilization that lead to the fetus receiving missing or extra chromosomes
An estimated two-thirds of early miscarriages are associated with chromosomal abnormalities. Usually it will not be related to later pregnancies and it does not mean that the parent's chromosome is abnormal.
The placenta is the connecting organ that provides the necessary nutrients from maternal blood to the fetus. If there is an abnormal placenta, it can lead to miscarriage.

Problems and abnormalities of the uterus that can lead to miscarriage in the middle 3 months include:
Uterine fibroids: muscle tumors develop benign in the uterus.
Abnormal shape of the uterus
In some cases, cervical muscle is weaker than normal called cervical insufficiency or cervical openings.
Cervical failure may be due to a previous injury, usually after cervical surgery. Weak uterine muscles cause the cervix to open too early in pregnancy, leading to miscarriage.
Polycystic ovary syndrome (PCOS)
PCOS is a condition where the ovaries are larger than normal, changing the hormones of the ovaries. PCOS leads to infertility due to reduced egg production, there is also some evidence that PCOS also increases the risk of miscarriage in women. However, the actual role of PCOS in miscarriage is unclear. No treatment has been proven to make a difference and most pregnant women with PCOS succeed without increasing the risk of miscarriage.
