Anterior Placenta

Any mummies has had anterior placenta? I've been pregnant before and this is my first time that the placenta is implanted on the front of my uterus. Gynae says it's normal so I don't need to worry. My baby is moving and kicking well though but he's in a breech position. When & at what week does your placenta goes up? My next scan will be at my 32nd week mark.
