Anyone have success with complete posterior previa moving after previous c section? Found at 20 week anatomy scan and go back in 4 weeks to check but he basically said my chances of having a VBAC are slim because it most likely wont move. Very dissapointed. Thinking he is saying that because he thinks it will attach to the scar tissue from my previous c section. Also reading that posterior are harder to move which im not sure has any truth to it. I would think if it was posterior it would have less chance of attaching.
