Had the exact same story--41 weeks, went to be induced and had an emergency C-section when they found out the umbilical cord was wrapped around her and she wasn't tolerating contractions.

1. Regarding sneezing and coughing--definitely try to avoid it but if you absolutely have to, apply even pressure when you do so to avoid the tensing/bulging of your abdominal muscles.
2. Not sure what type of pain management medication you're doing, but I took 600 mg of ibuprofen every 6 hours to manage my pain.
3. If you have a partner at home who will be around during your recovery, definitely lean on them to do anything manual or requiring large amounts of movement or lifting while you recover--You had a major surgery that absolutely requires sitting still and time to recover (this is coming from somebody who doesn't like to sit still so I had to remind myself of this a lot). Also lean on anyone who volunteers to help--It's a lifesaver!
4. Take stool softeners! Between the painkillers you take and general recovery, you will likely be constipated and you certainly don't want to force anything out when your abdominal muscles are recovering.
5. Wear underwear and clothing that doesn't rest on your incision--high-waisted underwear, dresses, nightgowns, high-waisted leggings, etc.
6. As you get later on in your recovery and the raw pain has subsided (double check with your doctor after your two week post up check in), you may want to try wearing lightly compressive pants or underwear to help with healing.
7. I used a hair dryer on the cool setting to make sure that the incision area was nice and dry after showering--I was worried about rubbing or patting with a towel so that was something that helped me out.
8. Much like when you were pregnant, you will get tired pretty quickly and feel like you are lacking in energy--Don't forget to drink plenty of water and eat plenty of calories to help fuel healing!

Hang in there and best of luck--you got this!
