Hope this helps! I had an EMCS after a long labour. It was a massive relief!
I showered the next day - my dressing was waterproof so no issues with that.
My catheter was removed as soon as the spinal had completely worn off which was about 12 hours.
Bleeding was similar - though didn't last quite as long after my c-section as it did after my vaginal births.
Not sure about baths as I don't have them!
Stitches are dissolvable so no need for removal. Had to have the waterproof dressing removed by the midwife after a week I think it was.
Big knickers that go way over your bikini line are perfect. My scar is at the top of my bikini line, and it's longer than I thought it would be!
Spinal was pure bliss! but I had been in labour (long induction) for ages so I could have snogged the anaesthetist. The worst part was sitting still but if you're not in labour then it's not an issue. It takes seconds and as soon as it's in you're numb.
I had my c-section at 3.30am, I was up walking 12 hours later, as soon as the catheter was removed. Best advice - keep as mobile as possible, it really helps to aid recovery. I kept up on my feet and upright as much as possible.
Other helpful things - Alternate between paracetamol and ibuprofen as needed. I was given liquid morphine too to self-administer but I honestly didn't find the pain that bad at all so never used it, but if you do need it - make sure you ask for it!
Pooping after a c-section (or any birth) isn't fun. Ask for some Lactulose to make it a bit easier. (I lost a lot of blood during the surgery and needed iron after which didn't help!)
If you have any concerns about healing afterwards, get it checked. My scar was a bit weepy, my midwife dismissed it but I saw the GP who gave me oral and cream antibiotics for an infection.
