This includes maternal age and other medical conditions present. Most doctors will begin to investigate for a cause after you have had two to three losses. This will include reviewing your medical history in detail and performing certain tests.

When the sperm and egg meet, the cells come together. They then begin to divide to start forming the genetic material that makes up a person. Each of us is supposed to have 46 total chromosomes.

If something goes wrong when the cells are dividing, a chromosome may be missing or repeated. About 50 percent of all first trimester miscarriages are because of chromosomal abnormalities. 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.

Avoid activities that could cause you to get hit in the belly. Know your family medical and genetic history.

Go to all of your scheduled prenatal visits and discuss any concerns with your doctor. Call your doctor right away if you have fever; feel ill; notice the baby moving less; or have bleeding, spotting, or cramping. Trying Again After a Miscarriage If you've had a miscarriage, take time to grieve. Some other things that can help you get through this difficult time: Find a support group.

This may worsen underlying health issues and further increase the chance of pregnancy loss.
