A threatened miscarriage is a condition that suggests a miscarriage might take place before the 20th week of pregnancy.

Threatened miscarriage; Threatened spontaneous abortion; Abortion - threatened; Threatened abortion

Some pregnant women have some vaginal bleeding, with or without abdominal cramps, during the first three months of pregnancy. When the symptoms indicate a miscarriage is possible, the condition is called a "threatened abortion." (This refers to a naturally occurring event, not medical abortions or surgical abortions.)

Miscarriage occurs in about half of pregnancies with first trimester bleeding.
