Miscarriage Statistics

The statistics behind miscarriage are actually quite astounding. For instance, the American Pregnancy Association says that 10-15% of clinically recognized pregnancies end in miscarriage. From the information I read that refers to a positive result in blood and or urine that a pregnancy exists as the HCG hormone is present.

Apparently though, many pregnancies end far before this point, though no one seems exactly sure how often. Estimates are up to 50% but those miscarriages you would never know occur. These would include the egg being released after it has been implanted. This happens so often though that most women only experience a slightly heavier period.

What we learn from all of this is that miscarriage is very common, this sounds scary, but the numbers of 10-15% means that only 1-2 out of 10 pregnancies that actually show up as positive on a home test will miscarry. Most women do not get pregnant 10 times in their lives, so your chances are even smaller of having a pregnancy that will fail while you are aware of it.

For those that still worry about miscarriage, here is some helpful news:
  • 80% of miscarriages happen within the first trimester and as Dr. Michael Roizen (author of YOU: Having a Baby ) states, most of these are due to chromosonal issues that would not produce a live birth. 
  • Once a heartbeat is present and considered normal the likelihood of miscarriage is very low between 4-13% with those who have bleeding at the higher end, and those without at the lower end. 
  • Additionally if you have had no previous miscarriage your risk is lower.
  • If you are under age 30 years old, your risk is between 10-15%, after 30 the risk raises slowly but can get up to 33% by age 42.
