Gave birth at 41 weeks and 5 days. No contractions, no dilation, they gave me a pill and bought it in just one day. I gave birth incredibly painful and long time without dilation. The cervix was long and tough like doctors said ?. The water was green, yellow, dirty ?. Luckily, I gave birth to a healthy baby, though I was afraid.
