Second trimester miscarriage

A second trimester (or ‘late’) miscarriage is one that happens after 12 and before 24 completed weeks of pregnancy. The majority of miscarriages occur within the first 12 completed weeks (first trimester) of pregnancy. Miscarriages occurring in the second trimester of pregnancy are uncommon and often unexpected. The incidence of miscarriage in the second trimester varies depending on the gestational age in weeks that is used in definitions and depending on whether the pregnancy has been dated and evaluated using ultrasound. Miscarriages during the first and second trimester of pregnancies have quite different causes, with second-trimester miscarriages more aligned to those of stillbirth.
