Definitely big high waisted knickers. I'm still in mine 4 months later (out of choice!). Primark do some good silky ones in packs of 3 in different colours and they actually look and feel quite nice.
You might not get the horrible trapped wind. I didn't, but I prepared for it with peppermint tea and peppermint capsules.
One of the best tips I got, relevant for VB or CS was to buy the Always discreet incontinence pads, and put a maternity pad in it. I only needed to do that for the time I was in hospital (one night) then when I got home it was just normal high waisted knickers and pads. My bleeding was totally manageable, but it can vary.
I wore nothing but over the bump maternity leggings and then high waisted jeggings for months after. I am actually still yet to wear anything that sits on the scar - but that's more because none of those clothes fit anymore 😂
We have a high bed, so I bought one of those exercise step things to put next to it so I didn't have to reach so far down to get out of bed. I didn't need to sleep propped up. Again, I bought a water bottle to use while laying down, but I didn't need it. Good to be prepared though!
I recovered very well and was doing an hour walk on day 8, so it's not always a really long recovery time. Just listen to your body though, and don't push yourself at all. I avoided bending down if I could for a while, and got my husband to do all the washing/dishwasher unloading etc for a couple of weeks, maybe a bit longer, but I did go on good walks because I felt I could, but I know I was lucky and this isn't the same for everyone.
I was also advised not to wash the area with perfumed soaps, and instead wash my body and let the wash just fall over it, and I also dried the area with a clean face cloth after every shower for a good couple of months (probably excessive!).
I don't know why but I found it really daunting walking into theatre. There are more people than you think there would be, and the bed looked so small in the huge room. Everyone was lovely though and it was all totally fine.
Also yes to lucozade sport!!!! It honestly was the best thing ever! My trust allowed me to drink it before as well but I think most places still make you not drink anything. Get yourself some good snack to see you through the night as well, also an eye mask is good for hospital, although personally I didn't sleep 😂
Also definitely have a pillow with you to put between your scar and the seatbelt for the drive home.
How exciting!
