Yesterday at my 20 wk scan the dr told me my placenta was low but not completely covering my cervix. So not quite placenta previa but close to it.  I have another u/s in 4 wks to check but in the meantime should I do anything different? The drs at the practice arent that helpful and are in and out so I wanted to ask here to those that maybe have more caring providers who spend more time and have some good advice.  Thanks!
