If the development of the pregnancy is not normal, pregnancy may fail. One may have a miscarriage if her fetus has problems with chromosomes. If the number of chromosomes in the fetus is more or less than the normal range of number, it may lead to miscarriage. Problems in chromosomes happen more often in the fetus, the parents of which are old or older. Especially pregnant women over 35 years old, the fetus of them suffer from the problems related to chromosomes. The higher the age of the pregnant woman is, the higher the risk of pregnancy failure is because of chromosomal problems in the fetus. A woman of 45 is at in much higher risk of pregnancy failure than a woman of 35 is.
Blighted ovum or ovum that has a severely detrimental effect is another common cause for pregnancy failure that occurs early in pregnancy, usually between the fifth weeks to sixth weeks of pregnancy. This period is just the period before the growing fetus will be visible in an ultrasound scanning machine. A blighted ovum is caused by chromosome abnormalities because of which the growing pregnancy cannot continue its healthy growth. So, the fertilized egg cannot develop into an embryo, but a cluster of cells forms in the uterus leading to an empty sac or bag or pregnancy. In some cases, the pregnant woman who has a blighted ovum remains completely unaware that she is pregnant in which situation she fails in pregnancy especially during surrogate motherhood like gestación subrogada.
