Women over 35 
http://www.healthline.com/health/pregnancy/risk-factors

As a woman ages, her chances of conceiving begins to decline. An older woman who becomes pregnant is also less likely to have a problem-free pregnancy. Common issues include:

1.Underlying conditions. Older women are more likely to have conditions such as high blood pressure, diabetes, or cardiovascular disease that can complicate pregnancy. When these conditions are not well controlled, they can contribute to miscarriage, poor fetal growth, and birth defects.

2.Chromosomal problems. A woman over 35 has a higher risk of having a child with birth defects due to chromosomal issues. When a woman is age 35, her chance of having a baby with a genetic disease is one in 178; by age 48, the chance rises to one in eight.Down syndrome is the most common birth defect related to chromosomes; it causes varying degrees of mental retardation and physical abnormalities. Prenatal screening and tests can help determine the likelihood of chromosomal complications.

3.Miscarriage. A woman age 35–39 is twice as likely to have a miscarriage as a woman in her 20s. About 35 percent of pregnancies end in miscarriage for women age 40–44. The risk increases to more than 50 percent at age 45.

4.Other complications. Women over 35 are more likely to havecomplications commonly associated with pregnancy regardless of age.
