Low lying placenta

Sarah • 💑💍👧🏽👦🏽🦔🐶🐶

I had my anatomy scan a few days ago. Baby girl looks great, is growing on track, but I have to come back for another scan in 4 weeks because they couldn’t get a great look at her heart since she was moving so much. I was also told my placenta was sitting lower than they like it. They say they want at least 2cm away from the cervix and mine is 1cm. Has anyone ever had this happen and had the placenta move?
