placenta accreta

I knew the placenta was an important aspect of pregnancy, but I was soon
to learn it had far deeper implications for pregnancy and delivery than
I had suspected.

Placenta accreta/percreta is a serious cause of intractable post-partum haemorrhage during caesarean section and a common cause of peripartum hysterectomy. 

Placenta previa, a medical condition characterized by a low attachment of the placenta over the cervical opening, can increase the risk of hysterectomy and excessive blood loss during C-section delivery.

A placenta creta, accreta, increta, or percreta is a placenta that grows during pregnancy into or through the uterus. Having this condition is life-threatening and requires expert surgical and medical care.

Complications of a cesarean section include bleeding, infections, injury to organs, and future placenta accreta and placenta previa.

What are my odds that I will have a placenta previa an accreta or another placental anomaly?
