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.
When you have your second trimester ultrasound scan at around 19 or 20 weeks of pregnancy, the sonographer will be able to see where the placenta has developed and will comment on its position in your ultrasound notes. This is where the fertilised egg first embedded itself into the wall of your uterus. The front wall of the uterus is called the anterior wall, the back wall is the posterior wall. The placenta may also be described as being 'fundal', which is right at the top of your uterus: in other words, the top of your bump.
