Low lying placenta

Any ladies not had any luck with a placenta moving out of the way? I have low lying placenta and waiting on a diagnostic scan in two weeks. I had an elective 3D scan last week and the tech said it's low still bit wouldn't say any more as it wasn't her place to be advising it. I am on pelvic rest and would love to hear from Mumma's who had late placenta movement?! Thank you in advance!
