My first child was not a good delivery. 3.5 years later I delivered my twins.
If something was wrong with the baby and you have been going in for regular visits to your gyno. Something would be detected. The chances of having a healthy baby far, far outweigh the chance s of not.
As far as the pain, it may seem silly but I realized that the easiest minutes of my labor was when the midwife guided me with my breathing.
Something so important you'd never know. I wish I would have been educated how to breath during labor, she must have thought I had an idea beacause she didn't stay with me on it. I went through hours, upon hours of pain but said again, the minutes she spent breathin with me, showing me how to breath was a bigger help than my epidural.
Good luck!!!
You'll do just find and the reward far outweighs the work!!!!!!
