white,
DS's birth was 'exciting'. He had - has - an abnormally large head, very long from front to back, and got very, very stuck. EMCS after failed trial of forceps, which saw 2 people pulling him out by his feet and one person pushing from 'below' to dislodge his head. When i went in to consult about whether to have VBAC or section for DD, I overheard consultant and a colleague discussing my notes, and it was only from the tone of alarm and concern in her voice that I really processed how unusually touch and go the whole thing was
DD was a textbook perfect VBAC. Short, straightforward labour.
What helped me was that there was a clear reason why DS got stuck, and by the time I went into labour with DD, I knew that it didn't apply to her. i had a late scan for her (36 weeks) and it showed that she had a normal, 50th centile head circumference. Therefore i went into the VBAC positively - there was no REASON why the same problem should occur, and so I truly believed it would all be OK. And it was.
For you, it is much the same. Once you get to labour, you will know that the reason for your EMCS hasn't happened again, so you can labour with optimism that there is no reason for there to be a problem. I think it is much harder when there has just been 'uunspecified failure to progress', leading to an EMCS in a first pregnancy, because there would always be the 'I don't know why it didn't work last time, so it might not work again' negative dialogue going on in your head.
