I had an U/S at 5.5 weeks, and the RE measured that my uterus was only 5mm (I think that was the measurement) thick. I didn't understand what she was telling me, so I asked if that was "good" or "bad." Response: not good. Do drs really consider the thickness of your U at the CS scar when measuring risk? I'm sorry to sound like an idiot. I'm at the beginning stages of exploring VBACs. My previous delivery that ended in a CS with a failed epi was urban-legend like, and I really don't think I could live through a repeat. Just looking for hope... Thanks!
