If the pregnancy is lost in the first 20 weeks, it is called the miscarriage. 10 to 20 percent pregnancies end in miscarriage. Usually the miscarriage happens in the first trimester. Miscarriage has some symptoms sp if you have these signs, you should immediately call your doctor.
The common symptoms of miscarriage include
Bleeding or spotting
The first sign of the miscarriage is the bleeding or the vaginal spotting. But every spotting or bleeding does not end in miscarriage.
This pain starts after you first have some bleeding. The pain is accompanied by cramps that are persistent, mild or sharp. Some women feel lower back pain or pelvic pressure.
Causes of miscarriage
- 50 to 70 percent of first-trimester miscarriages are due to chromosomal abnormalities in the fertilized egg. Usually when the egg or sperm had the wrong number of chromosomes, it results in miscarriage because the fertilized egg can’t develop normally.
- When an egg fails to get implanted in the uterus properly or an embryo has some kinds of defects in its structure then it will not develop properly.
- In many cases the cause of the miscarriage is unknown.
- In case of chromosomal problems in the fertilized eggs, the egg is implanted in the uterus and the gestational sac and the placenta start developing but the embryo fails to develop.
Chances of miscarriage
- When the age of the woman is more, the chances of miscarriage are high
- Women who are less than 35 yrs old have about a 15% chance of miscarriage
- The chances of miscarriage are 20 to 35 percent in women who are between the ages of 35-45 years.
- Women who are above 45 years have a 50% chance of miscarriage.
- A woman having previous miscarriage has a 25% chance to have another miscarriage.
Types of Miscarriages
When there is uterine bleeding in early pregnancy together with the cramping or lower back pain, it is called the threatened miscarriage.
Inevitable or Incomplete Miscarriage
When the cervix is open and bleeding occurs with the back and abdominal pain it is called the incomplete miscarriage. In an incomplete miscarriage, cramps and bleeding persist.
When the embryo empties out of the uterus, it is called the complete miscarriage. The bleeding, pain and cramping should subside quickly. The doctors can confirm the complete miscarriage with the help of the ultrasound or D&C.
When a woman has the miscarriage and she is unaware of it, it is called the missed miscarriage. In this condition the embryonic death occurs without its expulsion. It is only detected with the help of ultrasound.
Recurrent Miscarriage (RM)
When the miscarriage occurs 3 or more than 3 consecutive times in the first trimester, it is called the recurrent miscarriage.
It is also known as an embryonic pregnancy. In this pregnancy there is no fetal development but the fertilized egg is implanted into the uterine wall. There is no fetal growth.
