Slight bleeding may also occur in cases of trophoblast detachment or decidual haematoma (which later evolves into placenta). Fortunately, in most cases, this outer layer surrounding the embryo's cells resolves itself, and bleeding is not expected to interfere with the pregnancy or cause problems for the fetus. Bleeding may also occur in cases of molar pregnancy (a rare form of pregnancy in which the placenta develops abnormally), or an ectopic pregnancy (when the embryo develops outside the uterus).
