Sometimes, a pregnancy does not work out as we had hoped. This is very traumatic for both parents; their hopes are dashed and they must think seriously about the future of their unborn child. Often, complications are due to chromosomal abnormalities. If your caregiver detects something unusual in your ultrasound or alpha-fetoprotein test, you may be referred for a screening test. If, yet again, something is detected, you will go for diagnostic testing and will be referred for genetic counseling, which could provide insight about potential hereditary birth defects.
However, not all complications are related to chromosomal abnormalities. Irregular heartbeats can affect some babies. In many cases, these abnormalities correct themselves. If they don't, though, treatment will be required.
One complication many parents are concerned about is autism. While you may worry that something you do during your pregnancy will lead to autism in your child, this is unlikely. Autism and Pregnancy explains in more detail why this is.
Some complications can be caused by genetic defects carried by the mother. A genetic mutation, such as Methylenetetrahydrofolate reductase (MTHFR) can be carried through a whole life without any ill effects, but for some it can cause pregnancy complications and other health problems.
