Has anyone that previously had a c section been told they have a low lying anterior placenta? It is not covering my cervix but dr said the concern is that it could attach to my c section scar which is a big issue for this coming c section. He said they may have to do it early, but I don't understand why that would help. Anyone dealt with this or heard anything? I go back at 28 and 34 weeks, hopefully it will have moved up. I already had one preemie and really want to make it full term!
