Miscarriage: The Facts

According to the American Pregnancy Association:
  • The chances of having a miscarriage can range from 10-25%, and in most healthy women the average is about a 15-20% chance
  • An increase in maternal age affects the chances of miscarriage
  • Women under the age of 35 yrs old have about a 15% chance of miscarriage
  • Women who are 35-45 yrs old have a 20-35% chance of miscarriage
  • Women over the age of 45 can have up to a 50% chance of miscarriage
  • A woman who has had a previous miscarriage has a 25% chance of having another (only a slightly elevated risk than for someone who has not had a previous miscarriage)
  • Recurrent Miscarriage (RM): Defined as 3 or more consecutive first trimester miscarriages. This can affect 1% of couples trying to conceive.

According to WebMD:
  • (According to the March of Dimes) as many as 50% of all pregnancies end in miscarriage -- most often before a woman misses a menstrual period or even knows she is pregnant. About 15% of recognized pregnancies will end in a miscarriage.
  • More than 80% of miscarriages occur within the first three months of pregnancy. Miscarriages are less likely to occur after 20 weeks gestation; these are termed late miscarriages.
