So my first baby I had natural, no meds or anything. But took forever to dilate and when I did, it happened all at once. went from 3 to crowning within only a few minutes! But I had my last baby via emergency c-section for fetal distress (almost 7 years ago) I was having contractions but stuck at 3cm and he was sunny side up. it wasn't progressing fast enough. but anyways the doc told me today we are going to try natural but if I don't deliver by 41 weeks then it will automatically be a c-section because they don't induce a "scarred uterus". I'm nervous because of how slowly I dilated with my previous pregnancies. does anyone have experience with vbac? how did it go for you?
