Don't be shy in badgering the midwives for pain killers. They really don't tell you anything about pain relief. I had no idea how often I could/should have been taking pain killers (on the ward, this is, not at home) and they don't just come round and give them to you once the next lot are due. They seem to expect you to know when you're due some and then ask for them. In my case, I was (or at least should have been) on paracetamol 4 hourly and diclofenec 8 hourly. I was told off by one of the midwives for not keeping on top of the painkillers and that there was no need to be a martyr when I was in pain the next morning
. Thanks for that, midwives.
Definitely BIG pants. I'm normally a size 10 and got packs of size 14 granny bashers from M&S thinking they would be fine. I was a bit shocked at how big and swollen my stomach still was once baby was out and the size 14 were still a bit snug.
I was still wearing the big pants 4 months after the birth although have now reverted back to my normally little knickers now after my other half threatened to destroy all my big pants!
Whilst it'll be great once your baby is born and being introduced to you whilst you are being sewn up, don't do what I did and laugh too much when the midwife dropped a clanger about my baby's sex. Cue the surgeon sticking his head over the barrier and telling me to stop laughing and keep still as he had nearly stuck a needle through my bowel!
You'll probably get the shakes due to lowered blood pressure while you are on the table. This is completely normal and nothing to worry about. It's just nice to know in advance that it might happen so you can be be prepared for it.
When they get you up to have a shower the next morning and tell you to take the bandage off your stitches, the wound really will not look anywhere near as bad as you might imagine it will. I was terrified to remove the plaster, thinking it would be gross and I could do myself some damage. In reality, there were 5 little stitches and the wound looked really clean and neat.
Overall, I found the actual CS to be fine but being in pain and a bit swollen for weeks after the birth to be more difficult. Take it easy, don't lift anything other than your baby and keep taking the pain killers.
Good luck and I hope you really enjoy your birth.
