It must feel daunting, but your body is designed to cope and prepare your body for birth.
You will find as many horror stories as amazing birth stories.
It’s very very unpredictable, nobody can predict the outcome of any birth.
Therefore, it’s best to not worry.
What really helped me was the simple fact that every single woman at work/friends/etc had her baby and was fine.
You might think OMG how can I do this, you can, just like your mum and all other mums did. They always come out
My personal view (and it’s up to each woman to come to her own conclusion) is that a natural birth is much better for your body, once the baby is out, you are still yourself minus being temporarily sore.
When you have a C-section you are undergoing serious abdominal surgery with several layers of muscle being cut open that has to heal, you have additional infection risk that comes with any major surgery, your baby will not gain the important exposure to your bacteria, your recovery is longer and more difficult.
You will require more help after birth normally.
Like the other poster said, try to enjoy your pregnancy and re-check how you feel later on. Hopefully you will feel calmer and more sure about what you want.
