Hi Gem
As you know (I think you do anyway) I ended up with a section with Grace after a ventouse delivery with Christopher. I don't have the experience of being booked in for a section as it was an emergency but I imagine the experience being a lot calmer than being rushed into emergency theatre!
Yes it is painful after, BUT not as bad as you might imagine. I struggled turning over in bed for about a week but managed general things ok. What I would say though, is DONT overdo it as you will regret it! Your body doesn't let you do too much and will let you know it! Resist the urge to do some housework! Get some meals cooked and put in the freezer before you go in to hospital and get as much help as you can
oh and get a changing mat on a table downstairs as bending is a no no!
I personally had more pain after a vaginal delivery than with my section, I had an episiotomy that wouldnt heal as I contracted MRSA in the hospital! not to mention getting the stitches out and everything else lol!
Hope you can relax and think about the end product
I know you are gutted about missing out on your home birth
