What is early pregnancy loss?
The loss of a pregnancy before 20 weeks is called early pregnancy loss or miscarriage.
How common are miscarriages?
Miscarriages are surprisingly common. They occur in about 15% of known pregnancies.
What causes miscarriages?
Most miscarriages are caused by a random event in which the embryo receives an abnormal number of chromosomes. Sperm and egg cells each have 23 chromosomes. During fertilization, when the egg and sperm join, the two sets of chromosomes come together. An embryo with an abnormal number of chromosomes often cannot grow or survive.
What factors increase the risk of an embryo having an abnormal number of chromosomes?
The likelihood that an embryo will have an abnormal number of chromosomes increases as a woman gets older. After age 40 years, about one-third of pregnancies end in miscarriage, most as a result of this type of chromosome abnormality.
What are the signs and symptoms of the miscarriage?
Bleeding and passing clots are the most common symptoms of miscarriage. Mild cramping of the lower abdomen or a low backache also may occur.
If I have bleeding in early pregnancy, does it mean I am having a miscarriage?
A small amount of bleeding in early pregnancy is relatively common. Bleeding often stops on its own without treatment. However, if you have spotting or vaginal bleeding early in pregnancy, you should contact your healthcare provider. If your bleeding is heavy or occurs along with a pain like menstrual cramps, you should contact your healthcare provider right away.
What tests may be done if I have significant bleeding or cramping?
If you have significant bleeding or cramping, your health care provider may do an ultrasound exam. This exam can check whether the pregnancy is growing normally. If your pregnancy is advanced enough, the ultrasound exam can detect whether there is a heartbeat. Your health care provider also may do a pelvic exam to see if your cervix has begun to open (dilate).
If I have had a miscarriage, do I need medical treatment?
After a miscarriage, all of the pregnancy tissue may not be expelled. There are three options for removing this tissue:
1. If you do not have any signs of an infection, your health care provider may recommend waiting and letting the tissue pass naturally. This usually takes up to 2 weeks, but it may take longer in some cases.
2. You can take medication that helps expel the tissue. You will have bleeding, some of which can be heavy. Cramping pain, diarrhea, and nausea also can occur. You may pass tissue in addition to bleeding.
3. You can have a surgical procedure called vacuum aspiration. This procedure involves inserting an instrument or suction device into the uterus to remove the tissue. It often can be performed in your health care provider’s office. Risks of this procedure include bleeding, infection, and injury to internal organs.
The option that is used depends on many factors, including how far along in the pregnancy you were.
What precautions do I need to take after having a miscarriage?
After a miscarriage, you may be advised not to put anything into your vagina (such as using tampons or having sexual intercourse), usually for 2 weeks. This is to help prevent infection.
When should I have a follow-up visit with my healthcare provider after I have a miscarriage?
You should see your health care provider a few weeks after your miscarriage for a follow-up visit. Call your healthcare provider right away if you have any of the following symptoms:
- Heavy bleeding
- Severe pain
What if my blood type is Rh negative and I have a miscarriage?
If your blood type is Rh negative, you may receive a shot of Rh immunoglobulin after a miscarriage. The Rh factor is a protein that can be present on the surface of red blood cells. Most people have the Rh factor—they are Rh positive. Others do not have the Rh factor—they are Rh negative. During a miscarriage, it is possible for the mother’s blood to come into contact with fetal blood cells. If a woman is Rh negative and the fetus is Rh positive, this contact causes her to make antibodies against the Rh factor. These antibodies react against the Rh factor as if it were a harmful substance and can cause serious problems in a later pregnancy with an Rh-positive baby. Rh immunoglobulin prevents these antibodies from forming.
What can I expect to feel emotionally after a miscarriage?
The loss of a pregnancy—no matter how early—can cause feelings of sadness and grief. After a miscarriage, you need to heal both physically and emotionally. For many parents, emotional healing takes a good deal longer than physical healing. Grief can involve a wide range of feelings. You may feel sad and depressed one day, and angry the next. You may find yourself searching for a reason your pregnancy ended. You may wrongly blame yourself. You may have headaches, lose your appetite, feel tired, or have trouble concentrating or sleeping.
Will my partner have the same feelings as me?
Your feelings of grief may differ from those of your partner. Your partner also may grieve but may not express feelings in the same way you do. This may create tension between the two of you when you need each other the most. Partners also may feel that they need to be strong for you both and not show their grief.
How soon can I become pregnant after having a miscarriage?
You can ovulate and become pregnant as soon as 2 weeks after an early miscarriage. If you do not wish to become pregnant again right away, be sure to use birth control. If you do wish to become pregnant, you do not have to wait to begin trying again. You may want to wait until after you have had a menstrual period so that calculating the due date of your next pregnancy is easier.
