Early pregnancy loss
From Wikipedia, the free encyclopedia
Early pregnancy loss is a medical term that when referring to humans can variously be used to mean:
- Death of an embryo or fetus during the first trimester. This can happen by implantation failure, miscarriage, embryo resorption, early fetal resorption or vanishing twin syndrome.[1]
- Death of an embryo or fetus before 20 weeks gestation, as in all pregnancy loss before it becomes considered stillbirth.
