What is the risk to get first pregnancy at the age of 45 ? (for the baby and also for the mum's)

Below: Miscarriage rates begin to skyrocket in your 40s as well. At 40, the rate is 34 percent, and it rises to 53 percent by age 45. Your risk of pregnancy complications, such as high blood pressure and gestational diabetes, increases after 35 and continues to rise in your 40s. The odds of genetic problems also jump as you get older: At 40, your chance of conceiving a child with Down syndrome is one in 100; at 45 it's one in 30. Because the risk of genetic problems increase with age, experts routinely recommend that women in their 40s have detailed fetal screenings such as cell-free fetal DNA blood testing, advanced ultrasound, amniocentesis, or chorionic villus sampling. Mothers over 40 also have a nearly 50 percent chance of having a c-section as a result of delivery complications. Incidents of low-birth-weight and stillborn babies are higher as well.
