Can’t find a straight answer on Google, and my OB basically said I was wrong so.....

Can you be fully dilated but not fully effaced?

I was told my first labor ended in emergency csection bc the on call OB had me start pushing even tho the nurses said I was not fully effaced yet and baby went into distress from being in birth canal too long. I brought this up to my OB today and she basically said that’s not possible. Anyone know if this is or isn’t possible? I’m attempting VBAC which is why I’m asking.
