Tell them that you are saying no and the risk of spontaneous abortion (at 1-2%) following amniocentesis is higher than rupture from VBAC - and rupture is not always fatal. Some doctors / midwives need to put the "risk" into perspective but instead some of them persist with it. Meet them head-on re the evidence and ask THEM why with the 1% risk of rupture they maintain these ridiculous protocols. Ask them where is their evidence? What are the relative risks of repeat C/S? Ask them to demonstrate that they know the comparison. You can get support, try the Maternity Coalition and they will help. Cas McCullough has just launched CANA. If you want an advocate I am sure Cas could assist in some way.
