The loss of a pregnancy during the first 13 weeks of pregnancy (first trimester) referred to early pregnancy loss, miscarriage, or spontaneous abortion.
Early miscarriage is common. It occurs in about 10% of pregnancies are known.
Approximately one half of the cases of early miscarriages are caused by random events in which the embryo receives an abnormal number of chromosomes. Chromosomes are structures within cells that carry the gene. Most cells have 23 pairs of chromosomes for a total of 46 chromosomes. Sperm and egg cells each have 23 chromosomes. During fertilization, when eggs and sperm join, two sets of chromosomes come together. If the egg or sperm has an abnormal number of chromosomes, the embryo will also have an abnormal number. Development will not occur normally, sometimes resulting in the loss of a pregnancy.
Some women worry that they have done something to cause the loss of their pregnancy. Work, exercise, sex, or have used birth control pills before pregnancy does not cause early pregnancy loss. Morning sickness does not cause an early miscarriage. Some women who have had an early miscarriage believe that it is caused by a recent fall, blow, or even fear. In most cases, this is not true.
Smoking, alcohol, and caffeine has also been studied as a cause of early pregnancy loss. Some research suggests that smoking increases the risk, while other studies show that it is not. the use of alcohol in the first trimester may slightly increase the risk of early miscarriage, but the research is not clear. In any case, it is best to avoid smoking and drinking alcohol during pregnancy. Consuming 200 mg or less of caffeine a day (the amount in two cups of coffee) did not appear to increase the risk of early miscarriage.
The possibility of early pregnancy losses occur increases as the woman gets older. Early miscarriage occurs in more than one-third of pregnancies in women older than 40 years.
Bleeding and cramps are the most common symptoms of early pregnancy loss. A small amount of bleeding and cramping in early pregnancy is relatively common. Bleeding often stops on its own, and the pregnancy continues normally. Bleeding and cramping can also be signs of other pregnancy problems, such as ectopic pregnancy. If you have any of these signs or symptoms, contact your obstetrician-gynecologist (ob-gyn) or other members of your health care team.
If you have signs and symptoms of early pregnancy loss, you will most likely have a physical examination. your gynecologist will ask you questions about when the bleeding starts, how much you are bleeding, and if you have pain or cramping. Ultrasound examinations can be performed to check whether the embryo is still growing in the womb or detect the presence of a heartbeat. You may have a test to measure the level of human chorionic gonadotropin (hCG) in your blood. This substance is produced by the developing placenta. A low or decreased levels of hCG can mean the loss of a pregnancy. Some ultrasound exams and hCG tests may be needed to confirm that a miscarriage has occurred.
As the pregnancy is lost, some pregnancy tissue may remain in the uterus. These networks need to be removed. There are several ways this can be done. If the situation is not an emergency, you can help choose the type of treatment. The available options are equally at risk, including infection and heavy bleeding. The risk of serious complications, regardless of the type of treatment, it is very small.
If your blood type is Rh negative, you may receive an injection of Rh immunoglobulin after an early miscarriage. Problems can arise in a future pregnancy if you are Rh negative and Rh positive fetus. These problems can be prevented by giving Rh immunoglobulin after a miscarriage.
If you do not show signs of infection, one option is to wait and let the network to pass naturally. It usually takes up to two weeks, but may take longer in some cases. Another option is to take a drug that helps repel network.
You will experience bleeding. Bleeding is usually heavier than a menstrual period and lasts for a long time. Abdominal pain, diarrhea, and nausea may also occur. Your ob-gyn may prescribe pain medication. You can pass through the network in addition to bleeding. With early pregnancy loss, pregnancy tissue resembling blood clots. It does not look like a baby. Ultrasound examination or blood test for hCG is usually done afterwards to confirm that all of the network has been expelled. If not, you may need to have surgical treatment.
Surgery is recommended if you have signs of infection, severe bleeding, or other medical conditions. One surgical option called vacuum aspiration. In this procedure, a thin tube attached to a suction device inserted into the uterus to remove tissue. This procedure can be done in your doctor's office. Local anesthesia is used. You also may be given medication to help you relax. Another option is called dilation and curettage (D & C). In D & C, the cervix dilated (open), and the instrument used to remove the pregnancy tissue. A D & C is usually done in the operating room or surgery center. general anesthesia or regional anesthesia may be used.
You may be advised to not putting anything into your vagina (such as using tampons or have sexual intercourse) during 1-2 weeks after an early miscarriage. This is to help prevent infection. Ob-gyn call you immediately if you have the following symptoms:
If you or your partner is having trouble dealing with the feelings that go along with this loss, talk with the ob-gyn or other members of your health care team.

The first-trimester pregnancy loss is usually a one-time event. Most women go on to have a successful pregnancy. Repeated pregnancy loss is rare. Testing and evaluation can be done to try to find the cause if you have multiple pregnancy losses. Even if no cause is found, most couples will go on to have a successful pregnancy.
You can ovulate and become pregnant as soon as 2 weeks after an early miscarriage. If you do not want to get pregnant again soon, be sure to use a method of birth control. You can use contraceptive methods, including contraceptives has entered, immediately after an early miscarriage. If you want to get pregnant, there is no medical reason to wait to start trying again.
