Low anterior placenta

Hol 🌻

At my 12 week scan, my placenta was anterior. But they were hoping it would move by the time I had my next scan.

I'm now 19 weeks and at my morphology scan a few days ago, my placenta has stayed in the same spot. Still anterior. And over the cervix. Not completely sealing it, but overlapping. with a 1cm gap.

Has anyone had this and it moved by the third trimester? I'm worried about placenta previa.
