I was aiming for a homebirth and ended up with an emerg cs instead. I was really gutted about it, but tbh I had a really easy and quick recovery from the cs.
Take the pain relief they give you regularly and on time. This should keep the pain away (it's harder to get rid of the pain once it sets in apparantly).
Bathe every day and thoroughly pat your scar dry. I put lavender oil in my bath as it can promote healing.
Start drinking as much water as you can once you're back on the ward. As soon as your pee runs clear they can take the catheter out (although you probably will have to ask them to do it).
Get up and about as soon as you can. The blood circulating around your body helps the healing of your scar and will lower the risk of dvt. Am thinking a small stroll up the ward (with someone beside you) to start with. Then go a little further each time.
Be yourself and not a patient. You do have to take things easier, but you don't need to have everything done for you - iyswim.
Everytime you go to the loo, take a sanitary towel with you. You may bleed more than you expect, so to have to shuffle back to your bed to get another towel is a pain - quite literally!
I had my cs on Sun morning and was home for lunch the next day. I was highly motivated by not wanting to be there, but I also don't think I done anything out of the ordinary to get home so quick.
Good luck xx
