I had a low laying placenta at my 20 week scan (lots of people do) mine was completely covering my cervix so was told no sex and to be really careful, however after a few bleeds -all not related to placenta previa I was rescanned early and it's pretty much moved. Got another scan in 3 weeks to check it has moved completely out of the way xx

@littleelf85, thank you they said I need to be re scanned at 36 weeks but basically said not to worry. Just been researching it and most of the things has scared me
