Placenta is rolling ??

So I had my anatomy scan on Wednesday. During the scan the lady doing the scan paged a specialist. So I was seen by a specialist during the scan because the lady noticed something wired .. I was notified by the specialist that my placenta is rolling upwards & not staying flat out where it’s supposed to. My pregnancy is now considered chronic. The specialist set up for me to go back every week and go see her . She also referred me to another specialist to get a second opinion but that she was 100% sure of what she was seeing. I see my OB in 2 days & they’ve already called me to notify me they have the results from the anatomy scan & the new referral to see the second specialist.

I was told all this info by the specialist who saw me. I did not diagnose myself.

Has this happened to someone else ?? What happens after ?
