First off hon, they will try to section you as close to 39 weeks as possible even after as its safest for baby though your spd may play a part in a slightly earlier one.
I had a spinal and it was brilliant,much better than my epidural that never worked.
Didnt feel the spinal go in just a warm feeling as i lost feeling if that makes sense.
My section was an emergency but i can honestly say i never had any pain at all afterwards,i never used pain killers once i discharged my self from hospital(they wantes me to stay 5 days but i wanted 2).
I pretty much carried on as normal after my section, going shopping, going for walks,making tea, visiting etc-the only thing that i couldnt really do for about 10 days was sit on floor or reach up.
Would def say after have warm salt water baths as its brilliant for scar healing after 6 months mine was practically gone.
Goodluck hon,you will be fine.xxx
