Miscarriage is defined as an early pregnancy loss that occurs at less than 20 weeks’ gestation. Miscarriages are common and become more common the older you get, ranging from about 1 in 6 known pregnancies for younger women to 1 in 3 or older women. Miscarriage can be due to a number of reasons and the most common cause is a chromosomal abnormality that is not compatible with life. About 95% of miscarriages happen very early, usually before six weeks’ gestation. 

After multiple miscarriages, there are certain conditions we can test for that are associated with recurrent pregnancy loss. Late pregnancy losses (after 20 weeks) are always investigated because these are more likely to be due to a specific cause. 

Miscarriage can be a very disheartening thing, but a single miscarriage does not increase your risk of having another miscarriage! That is very important to know.
