Enlarged/Thickened Placenta

Bria

My last two ultrasound showed that I had an enlarged Placenta but they baby is growing find.. All my test came back fine no abnormalities or infection.. They say it's nothing to worry about but I know it's a risk for premature labor.. I'm already at risk for having preemies.. I really don't need anything to add on to it.. Has anyone ever been through this before.. I'm 23+3 today wit a baby girl..
