- The umbilical cord connects the fetus to the placenta, allowing materials to be transferred.

Anterior placenta: The placenta develops on the front of the uterus with the fetus behind it. It could make it difficult for you to feel the fetal kicks and for sonographers to find the heartbeat. It may lead to placental abruption, intrauterine growth restriction, and fetal death (19).
Where is the placenta previa located?
Placenta previa: It occurs when the placenta lies low in the lower uterine segment of uterus and covers the opening of the cervix partially or totally. It may, therefore, block the baby’s exit from the womb, resulting in preterm labor, placental tear, and antepartum and intrapartum hemorrhage (14) (15).
