Complications of the Placenta Placenta previa without bleeding does not seem to affect the baby’s likelihood of surviving childbirth. Placental abruption Placental abruption is a condition where a part of the placenta separates from the uterus during pregnancy. There are many blood vessels within the placenta that transfer nutrients from the mother to the unborn baby. If the placenta detaches during pregnancy, these blood vessels break, and thus there is bleeding.

Is it bad if I bleed when I am pregnant? This is an obstetrical emergency.

Pregnancy Complications: Placenta Accreta Placenta accreta is a serious pregnancy complication that can occur when the placenta attaches itself too deeply into the uterine wall. Placenta accreta is a serious pregnancy complication that can occur when the placenta attaches itself too deeply into the uterine wall. This causes part or all of the placenta to stay firmly attached to the uterus during childbirth. Placenta accreta can result in severe bleeding after delivery. According to the American Congress of Obstetricians and Gynecologists (ACOG), 1 in 533 American women experience placenta accreta each year. In some cases of placenta accreta, a woman’s placenta will attach so deeply into the uterine wall that it attaches to uterine muscle. This is called placenta increta. It can even go more deeply through the uterine wall and into another organ, such as the bladder.

Complications of the Placenta With marginal placenta previa, the placenta implants near the bottom part off the uterus and may block part of the cervix. The baby may need to be delivered by caesarean section. Placenta previa is a common cause of bleeding during late pregnancy. In the second trimester, the bleeding should stop with bed rest, either at home or in the hospital. If you have bleeding in the second trimester that does not stop, you will be monitored in hospital and possibly given blood transfusions.

Low-Lying Placenta (Placenta Previa) If the placenta attaches to the lower part of the uterus, it can cover part or all of the cervix (the entrance to the womb). When the placenta covers part or all of the cervix during the last months of pregnancy, this is a condition known as placenta previa, or low-lying placenta. This condition can cause severe bleeding before or during labor.

Any bleeding from placenta praevia at the entrance to the womb in the second half of the pregnancy can be heavy and a risk to the baby and the mother's health. After a low-lying placenta diagnosis, seek medical advice if there's any bleeding during pregnancy.

Previa, Accreta, Abruption, Oh My!: Understanding Problems with the Placenta in Pregnancy Placenta previa usually doesn’t cause any problems with the baby’s growth and development, but it can cause problems for the mother. Occasionally, placenta previa can result in vaginal bleeding in the second or third trimester, which is usually painless and bright red in color. If a vaginal delivery is attempted, the placenta can tear, leading to very heavy bleeding (peripartum hemorrhage), which can endanger the life of both the mother and baby.
