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.
Common First Trimester Miscarriages
Most miscarriages happen between 6 and 8 weeks gestation. We know that most of these occur due to a major genetic abnormality in the fetus. The sperm and the egg (which are known as gametes) each contain half the genetic material necessary for a complete person.
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.
Chromosomal abnormalities in the fetus are the most often cause of missed miscarriages, since these abnormalities do not allow the pregnancy to develop.
If a miscarriage happens during the first 3 months of pregnancy (known as early miscarriage), it's usually caused by chromosomal abnormalities in the baby. These happen by chance. Chromosomes are blocks of DNA, which contain instructions for your baby's development.
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).
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.

Risk of miscarriage by week of pregnancy
According to one study, once a pregnancy gets past 6/7 weeks and has a heartbeat, the risk of having a miscarriage drops to around 10%.
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.
Do not eat raw or undercooked meat, chicken, or fish (such as sushi or raw oysters). Do not eat raw eggs or foods that contain raw eggs, such as Caesar dressing. Do not eat raw sprouts, especially alfalfa sprouts. Do not eat soft cheeses and unpasteurized dairy foods, such as Brie, feta, or blue cheese.
Easing Your Miscarriage Fears
Try to remember that your fears are normal, but that this phase will pass. Take time to practice mindfulness, meditation, and take some time for yourself. This could include any stress-reducing activities you enjoy like yoga or going for a walk.
Even in your third trimester of pregnancy, bending is still considered safe for your baby. You'll probably find it becomes increasingly difficult for you, though, if not impossible. Apart from your extra body weight, the size of your belly is increasing.
NIH Study on Caffeine
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.
First Trimester (0 to 13 Weeks)
The first trimester is the most crucial to your baby's development. During this period, your baby's body structure and organ systems develop.
The nuchal translucency screening (aka NT Scan) typically happens between weeks 10 and 14; it tests your fetus for risk of Down syndrome and several other chromosomal abnormalities. For it, you'll have a painless ultrasound, and baby's nuchal fold (back of the neck) will be measured for signs of abnormality.
Even though it's called morning sickness, it can last all day and happen any time of day. At least 7 in 10 pregnant women have morning sickness in the first trimester (first 3 months) of pregnancy. It usually starts at about 6 weeks of pregnancy and is at its worst at about 9 weeks.
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.
Sage tea: It's OK to use sage in cooking, but you should avoid sage in concentrated forms during pregnancy such as in teas. It's been linked to miscarriage and high blood pressure.
Pregnant women are often advised to wait until they pass the 12-week mark, when the risk of miscarriage drops sharply, to announce their pregnancies to the world.
