Recurrent early miscarriages (within the first trimester) are most commonly due to genetic or chromosomal problems of the embryo, with 50-80% of spontaneous losses having abnormal chromosomal number. Structural problems of the uterus can also play a role in early miscarriage.
What causes miscarriage? Chromosomal abnormalities cause about 50% of all miscarriages in the first trimester (up to 13 weeks) of pregnancy. Chromosomes are tiny structures inside the cells of your body that carry your genes.
The risk of miscarriage drops significantly as pregnancy progresses. In one study, researchers found a miscarriage rate of 9.4 percent at 6 weeks of pregnancy, 4.2 percent at 7 weeks, 1.5 percent at 8 weeks, 0.5 percent at 9 weeks and 0.7 percent at 10 weeks.
About half of early miscarriages happen when the embryo does not develop properly. This often is due to an abnormal number of chromosomes. Chromosomes are in each cell of the body and carry the blueprints (genes) for how people develop and function.
Most miscarriages - 8 out of 10 (80 percent) - happen in the first trimester before the 12th week of pregnancy. Miscarriage in the second trimester (between 13 and 19 weeks) happens in 1 to 5 in 100 (1 to 5 percent) pregnancies. Pregnancy loss that happens after 20 weeks is called stillbirth.
Certain uterine conditions or weak cervical tissues (incompetent cervix) might increase the risk of miscarriage. Smoking, alcohol and illicit drugs. Women who smoke during pregnancy have a greater risk of miscarriage than do nonsmokers. Heavy alcohol use and illicit drug use also increase the risk of miscarriage.
The risk of miscarriage also decreases significantly—to about 5 percent—after your doctor detects a heartbeat. This typically occurs at around your 6 to 8 week mark. The chances of having a second miscarriage after a woman has already experienced one is also very slim at less than 3 percent.
There are three main treatments for early pregnancy loss.
There are two nonsurgical treatments: expectant management (letting the tissue pass on its own) and medication. The third treatment is a surgical procedure called dilation and curettage (also known as D&C or suction curettage).
If you miscarry naturally, even in the early weeks of pregnancy, you are likely to have period-like cramps that can be extremely painful. This is because the uterus is tightly squeezing to push its contents out, like it does in labour – and some women do experience contractions not unlike labour.
Here's the good news: According to a study, after an ultrasound confirms baby's heartbeat at eight weeks, the risk of miscarriage is about 3 percent. Better yet, research published in Obstetrics & Gynecology indicates that the rate is closer to 1.6 percent for women experiencing no symptoms.
The short and reassuring answer is: no. There is no direct link between stress and having a miscarriage. While some studies suggest that stress can increase the risk of miscarriage, they do not show a direct cause-and-effect relationship.

Many physicians advise pregnant women to sleep on their left side. Previous studies have linked back and right-side sleeping with a higher risk of stillbirth, reduced fetal growth, low birth weight, and preeclampsia, a life-threatening high blood pressure disorder that affects the mother.

In addition, women also are more likely to miscarry if they drink more than 200 mg of caffeinated beverages a day during the first seven weeks of pregnancy.
We know that miscarriages occur in at least 15% of confirmed pregnancies. The actual miscarriage rate is likely to be much higher – we estimate it to be around 1 in 4 pregnancies. Based on these rates and the number of births each year, we estimate around 285 miscarriages occur every day in Australia.

Your nausea and vomiting may be worse than ever: Morning sickness peaks around 9 or 10 weeks of pregnancy for many women. That's when levels of the pregnancy hormone human chorionic gonadotropin (hCG) are highest (morning sickness is thought to be linked to rises in hCG and estrogen).

By 7 weeks, the embryo has grown to about 10mm long from head to bottom. This measurement is called the crown-rump length. The brain is growing rapidly and this results in the head growing faster than the rest of the body. The embryo has a large forehead, and the eyes and ears continue to develop.

There are several reasons why you might not see the fetus's heartbeat at eight weeks. First, you may not really be eight weeks pregnant. You may have menstrual cycles longer than 28 days, or you may have ovulated late that cycle. The second reason has to do with the type of ultrasound probe your doctor is using.
FGR can happen when the placenta is not working well enough to provide the baby with the nutrients they need to grow normally. However, we don't always know why FGR happens. Sometimes it can be caused by other conditions, such as chromosomal problems or infections, such as cytomegalovirus or toxoplasmosis.
