A missed abortion or missed miscarriage is when the embryo or fetus dies and a miscarriage has not yet occurred. There is early fetal intrauterine death, and products of conception are not expelled.
This type of abortion does not cause symptoms of bleeding or cramps like in other abortions. There may be a dark brown vaginal discharge, pregnancy symptoms, breast soreness, nausea, or negative pregnancy test.
Most miscarriages occur due to the embryo having the wrong number of chromosomes. Miscarriages can often be caused by uterine problems. These women may have endocrine or autoimmune disorders or may be heavy smokers.
Missed-in a missed abortion, there is early fetal intrauterine death, and products of conception are not expelled. the cervix remains closed; there may be a dark brown vaginal discharge, negative pregnancy test, and cessation of uterine growth and breast tenderness. a threatened abortion is evidenced with cramping and vaginal bleeding in early pregnancy, with no cervical dilation. an incomplete abortion presents with bleeding, cramping, and cervical dilation. an incomplete abortion involves only expulsion of part of the products of conception and bleeding occurs with cervical dilation.
