Usually the placenta positions itself at either the top or side of the uterus. But itâs always possible that the placenta will attach to the front of the stomach, a position known as an anterior placenta. If the placenta attaches to the back of the uterus, near your spine, this is known as a posterior placenta. Typically, your doctor will check the position of your placenta during your mid-pregnancy ultrasound, which should take place between 18 and 21 weeks of pregnancy.
A placental abruption (abruptio placentae) is when a normally implanted placenta separates from the uterus after 20 weeks gestation (less then 20 weeks gestation is considered a spontaneous abortion). It occurs in approximately 0.5-1% of pregnancies in North America (Broers et al, 2004).he classical presentation is that a placental abruption is painful bleeding and a placenta previa is painless, however a woman with a placenta previa can also be contracting and thus can be in pain as well. A pelvic exam should not be done until a placenta previa can be ruled out as this can trigger further bleeding.
