Ya im not sure what you mean by too late. But i will always give myself the full 42 weeks b4 being induced unless there is a verified medical reason not to. I think it would be extremely rare that a woman would not go into labour on her own within 42 weeks if only more women insisted on giving their bodies sufficient time.
Why were you induced? You should tell your doctor how you feel best of luck
Why would it be too late? Your body will most likely know what to do. The previous inductions have no effect on this one.
