Does the uterus tear while giving birth? i'm afraid of amniotic fluid embolism although i know it's rare.

Any risk factors?: Uterine rupture occurs usually when the scar of a previous C-section tears open and is rare. Multiple prior C-sections are risk. AFE occurs when amniotic fluid or fetal cells or hair enter the maternal circulation leading to complications in the mother and is rare . Risk factors include multiparty, advanced maternal age, male fetus and trauma and uterine rupture. Discuss risk factors if you have.
