Hi. I'm 21 plus 1 with baby number 7. At my 20 week scan I was diagnosed with major placenta previa. It's totally covers the os and is based left laterally. Anyone else had this? And what's the chances of it moving? The sonographer isn't so sure it will move. I'm being re scanned at 32 weeks. I've not bled since early pregnancy. Been told to stop intercourse. Would love to hear from anyone else that has had this. Ta xx
