This can occur more frequently in women who are considered advanced maternal age, or greater than 35 years old at pregnancy term. Uterus or cervix infections can be dangerous to a developing baby and lead to miscarriage. Other infections that may pass to the baby or placenta can also affect a developing pregnancy and may lead to loss. This refers to defects of the uterus cavity. Clotting disorders are conditions that cause your body to form more blood clots than normal.
Examples include lupus anticoagulant and antiphospholipid syndrome. In the case of pregnancy, blood clots can form in the placenta. This prevents nutrition and oxygen from getting to the baby-to-be, and prevents waste from being carried away.
The first trimester of pregnancy is considered weeks 0 to About 80 percent of miscarriages happen in the first trimester. Losses after this time occur less often. March of Dimes reports a miscarriage rate of only 1 to 5 percent in the second trimester. These early weeks mark the highest risk of miscarriage.
It may even seem like a late period. One study indicated that compared to women younger than Once a pregnancy makes it to 6 weeks and has confirmed viability with a heartbeat, the risk of having a miscarriage drops to 10 percent. According to a study , the risk for miscarriage falls quickly with further gestational age. However, this was not specifically studied in patients with other risk factors for miscarriage. By week 12, the risk may fall to 5 percent.
The most common signs of a miscarriage are bleeding and cramping that are felt in the abdomen, pelvis, or lower back. Some women have spotting light bleeding during pregnancy. But call your doctor right away if you see bright red blood, particularly in large amounts. Cramping can also happen in normal pregnancies. The majority of miscarriages are the result of genetic abnormalities or other health factors that are beyond our control.
The best thing you can do is to keep yourself as healthy as possible before trying to conceive and throughout your pregnancy. Here are some tips to staying healthy during pregnancy:. A blood sample will be taken from one or both partners, and then sent to a laboratory to be evaluated for major genetic disorders. This testing and other evaluation are generally done after someone has recurrent losses. The experience of a miscarriage can be physically and emotionally painful.
Talk to trusted friends and family, and ask for help when you need it. Your doctor may be able to recommend a support group or therapist in your area. This content does not have an Arabic version.

But just to be safe, if you have spotting or any of these other symptoms anytime during your pregnancy, talk with your doctor. Many experts define a stillbirth as the death of a baby after the 20th week of pregnancy. It can happen before delivery or during labor or delivery. A stillbirth also is sometimes referred to as intrauterine fetal death or antenatal death. There are some known risk factors for stillbirth, such as smoking, obesity, problems with the placenta, a pregnancy lasting longer than 42 weeks, and some infections.
The most common sign of a stillbirth is decreased movement in the baby. If you notice your baby moving less than usual, call your doctor right away. Your doctor can use an ultrasound to look for the heartbeat or, later in pregnancy, give you a fetal non-stress test. This involves lying on your back with electronic monitors on your abdomen. The monitors record the baby's heart rate and movements, and contractions of the uterus. The most common cause of pregnancy loss is a problem with the chromosomes that would make it impossible for the fetus to develop normally.
If a woman miscarries, her doctor will do a pelvic exam and an ultrasound to confirm the miscarriage. Sometimes, the uterus still contains the fetus or other tissues from the pregnancy. A doctor will need to remove this. The doctor may give medicine to help pass the tissue or may dilate the cervix to do:.
After the delivery, the doctor will have the baby and the placenta examined to help find the cause of death if it's still unknown. Women who have had several miscarriages may want to get checked to see if any anatomic, genetic , or hormonal problems are making miscarriages more likely. Still, some things — such as smoking and drinking — put a woman at a higher risk for losing a pregnancy. Good prenatal care can help moms and their babies stay healthy throughout the pregnancy.
If you've had a miscarriage, take time to grieve. The loss of a baby during pregnancy is like the loss of any loved one.
