It's called Anterior placenta, which means its in front of the baby i.e. between your front and baby. Posterior Placenta is opposite side, so at the back between your back and baby. Then there is the placenta pravia which means it is low down in the uterus and sometimes it can be blocking the opening meaning ladies having to have a c-section.
So you have Anterior, like me! Very common, and like others say i think it can cushion some of the movements so they don't feel as strong so early on.
