Normally, the placenta is attached to the uterus above the cervix. In rare cases, the placenta forms low in the uterus and is partially or completely covering the cervix. When the placenta is blocking the cervix, it is called placenta previa. Placents posterior mean high risk in doctor's language Posterior means back.
The OP position (occiput posterior fetal position) is when the back of babyâs head is against the motherâs back. Here are drawings of an anterior and posterior presentation. Look at this drawing. The posterior babyâs back is often extended straight, even arched, along the motherâs spine. posterior presentation aims the top of the head into the pelvis, i.e. oblong, rather than the circle of the crown. The anterior babyâs head enters the pelvis from the crown of the head first. The crown molds more easily.
